# Square Root Calculator

Square Root calculator enumerates the square root of the given number. Square Root is a branch of mathematics that deals with the number in such a way that if the square root value is multiplied by itself then, it gives the original number.

## What is a Square Root Calculator?

Square Root Calculator is an online tool used to calculate the square root for the given number such that when the square root values are multiplied by themselves, it gives the original number. It helps to calculate the square root in a few seconds. To use this** square root calculator**, enter values in the input box.

## What is the Square Root of a Number?

The square root of a number is a number that, when multiplied by itself, gives the product as the original number. Let us understand this better with an example.

Let us find the square root of 5

We know that, 5^{2} = ( 5 × 5) = 25

Here 5 is called the square root of 25. Therefore, 25 is a perfect square.

## How to Use the Square Root Calculator?

Follow these simple steps to calculate the square root using an online square root calculator:

**Step 1**: Go to Cuemath’s online square root calculator.**Step 2**: Enter the number in the input box of the square root calculator.**Step 3**: Click on the "Calculate" button to find the square root of the number.**Step 4:**Click on the "Reset" button to clear the fields and enter new values.

## How Square Root Calculator Works?

The square root of the number '**n'** can be written as '**√n'**. It means that there is a number 'a' when multiplied again with 'a' gives 'n':

a × a = n

This can also be written as:

a^{2 }= n or a = √n

So, a is equal to the square root of n.

Now, if n = 89, then a = √89 is the square root of 89. In the radical form, the square root of 89 can be represented by √89

The square root of 89 = 9.43 in the decimal form up to 2 decimal places.

## Solved Example on Square Root

**Example 1:** Find the square root of 64 and verify it using the square root calculator.

**Solution: **

We know that the square root of a number(n), a = \(\sqrt{number,n}\)

\(a = \sqrt{n}\\ \,\,\,= \sqrt{64} \\ \,\,\,= \sqrt{8 \times 8}\\ \,\,\,= 8 \)

Therefore, 8 is the square root 64

Similarly, to find the square root of the number, you can try the square root calculator for the following:

- 800
- 216
