## What is the square root of 28?

In search of questions, people and topics, we came across the following question: What is the square root of 28? The answer is that it is between 5 and 6. Although there are algorithms to calculate it, nowadays the calculator is used more. However, mentally it is convenient to make squares to obtain the whole part of the root.

## What is the square root of 9?

The square root of 9 is calculated by finding the number that, when multiplied by itself, is 9. In this case, that number is 3. Therefore, the square root of 9 is 3.

If we already know the powers, we can look for the number that, when squared, gives us 9. In this case, that number is 3, since 3 squared is equal to 9.

It’s very simple, right? Now you can try to calculate the square root of 16. Have you found it yet? It is 4, since 4 squared is equal to 16.

To better understand the concept of square root, let’s look at some visual examples.

## What is the square root of 121?

The square root of 121 is equal to 11, since 11 multiplied by 11 is equal to 121. To determine if the square root of 121 is greater than, equal to, or less than the cube root of -42, we can use a few properties.

First of all, we know that the cube root of any negative number will always be negative, while the cube root of a positive number will always be positive. Therefore, the cube root of -42 will be a negative number.

When calculating the cube root of -42 on a calculator, we get approximately -3.48 rounded to two decimal places.

Since 11 is greater than -3.48, we can conclude that the square root of 121 is greater than the cube root of -42. This is confirmed by checking the answer on the calculator.

## What are the numbers that do not have a square root?

In the first exercise, the result of a power known as the base and the exponent is calculated.

In the second exercise, the base of a root known as the exponent 2 and the result are calculated.

The exact square root of an integer is another integer whose square is equal to the original number.

Not all integers have an exact square root, only those called perfect squares. However, it is possible to find an integer approximation of the square root.

The integer square root of a number is the largest integer whose square is less than or equal to the original number. The remainder of the integer square root is the difference between the original number and the square of its integer square root. The symbol “≈” is used to indicate that it is an approximation.

It is important to note that the square root of a positive number always has two values, one positive and one negative, since when squaring the sign is always positive. The only number that has a single square root is zero.

For this reason, there are no square roots of negative numbers.

## What is the square root of 60?

Powers and square roots are fundamental concepts in algebra.

In the case of exact square roots, we can identify numbers that are perfect squares, such as 25 (the square of 5) and 49 (the square of 7). Therefore, we will say that the square root of 25 is 5 and the square root of 49 is 7.

The square root operation is represented by the symbol √.

The number whose square root we want to calculate is called the radind. In the example above, the radind is 25.

Calculating the square root of a number is the inverse operation of calculating the square of the number. Geometrically, calculating the square root of a number is equivalent to finding the length of the side of a square whose surface area is equal to the given number.

Using the table of perfect squares, we can calculate the square root of the following numbers: 4, 9, 36, 81, 100, 121 and 225.

In the case of inexact square roots, such as the number 60, we cannot find a natural number that is its exact square root. However, we can determine that the square root of 60 will be between the square root of 49 (7) and the square root of 64 (8).

We will then say that 7 is the integer square root of 60. The difference between 60 and the square of 7 (49) is 11, which is called the remainder of the square root.

We can calculate the integer square root and the rest of other numbers and check the results in practical exercises.

## How to calculate the value of a root?

In the Square Roots Section we learned about square roots. Remember that the square root of a number is the number that is multiplied by itself to obtain a product. In essence, it is the number that is squared. Square roots and squares are inverse operations. You can square a number to get a product and then take the square root of that product to get back to the original number.

Here you can see the inverse operation between raising a number and finding the square root of a product.

A number like 36 is a perfect square, meaning its square root is a whole number. Here are some other perfect squares: 16, 25, 36, 49, 64, 81, 100, 121, 144, 169. If you find the square root of these numbers, you will get a whole number as your answer.

But what if the square root is not an integer? In that case, we can approximate the square root of the number. There are two different ways to do this.

The first way is using perfect squares. To do this, we look for perfect squares that generate a number close to the square root we are looking for. For example, if we look for the square root of 30, we first find two perfect squares close to 30. One must be less than 30 and another greater than 30. In this case, the perfect square less than 30 is 25 and the perfect square greater than 30 is 36. Because 30 is between 25 and 36, we can say that the approximate square root of 30 is between 5 and 6. It is probably close to 5.5.

The second way to approximate a square root is by using a calculator. Calculators have a radical sign. To find the square root of a number, we press the radical sign, then enter the value, and finally press enter. This will give us a decimal approximation of the square root. Many times we will have to round these answers.

The third way to approximate a square root is using tabular interpolation. This involves using a table to find the approximate value of the square root. We can find tables that include numbers up to 100 and use them to find the square root of numbers 1 to 100.

In summary, there are different methods to find an approximate square root. We can use perfect squares, calculators or tabular interpolation. In all cases, it is important to round the answer to the nearest tenth.

## What is the square root of 49?

ESTATE

Roots are a mathematical concept that refers to the inverse operation of calculating the square of a number. In particular, we will focus on the square root, which consists of finding the number that, when squared, results in the given number.

For example, we know that 25 is a perfect square, since it is the result of squaring 5. Therefore, we will say that 5 is the square root of 25. Similarly, the number 49 is the square of 7, so we will say that 7 is the square root of 49. This operation is represented by the symbol Ö.

To calculate the square root of a number, we simply find the number that, when squared, results in the given number. For example, Ö25 is equal to 5, since 5 squared is equal to 25. The number whose square root we want to calculate is called the radind.

Geometrically, the square root of a number is equivalent to calculating the length of the side of a square whose surface area is equal to the given number. That is, if we have a square whose area is 25, the length of each side will be 5.

In some cases, the square root is not exact and is not a natural number. For example, the number 60 is not a perfect square. In this case, the square root of 60 will be between the square root of 49 (which is 7) and the square root of 64 (which is 8). Therefore, we will say that the whole square root of 60 is 7.

Additionally, we can calculate the remainder of the square root, which is the difference between the given number and the square of the integer square root. For example, in the case of the square root of 60, the remainder is 11, since 60 – 72 = 11.

To practice calculating square roots, we can use the table of perfect squares. For example, the square root of 4 is 2, the square root of 9 is 3, the square root of 36 is 6, the square root of 81 is 9, the square root of 100 is 10, the square root of 121 is 11 and the square root of 225 is 15.

In summary, square roots are a mathematical operation that allows us to find the number that, when squared, results in the given number. This operation has properties and allows us to calculate both the entire square root and the remainder of the square root.
