## What is Square Root of a Number?

The square root of a number is a number that, when multiplied to 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. 25 is a perfect square. So, the square root of 25 is 5.

## How to Use the Square Root Calculator?

**Step 1**: Enter a number in the input box.**Step 2**: Click on "**Calculate**" to find the square root value of the number.**Step 3**: Click on "**Reset**" to clear the field and enter the new number.

## How to Find Square Root of a number?

The square root of a 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

^{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:**

Find the square root of 64.

**Solution: **

We know that 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.
