What is Square root?

The square root is the inverse operation of the square.

For example,

The square of 4 is 16. Thus, the square root of 16 is 4.

How to represent a square root?

The square root is represented by the symbol, √ , also known as the radical.

The number inside this symbol is called the Radicand or Base.

For example,

The square root of 16, is written as √16.

How to find the square root of a number in exponential form?

To find the square root of a number in exponential form, keep the base the same and halve the exponent.

For example,

To find √24, we keep the base the same, which is 2, and halve the exponent. So, half of 4, which is 2.

So, √24 = 22 = 4.

Let us verify this.

24 = 16

∴ √24 = √16

∴ √24 = 4
