The square root of a number is a value that, when multiplied by itself, gives the original number. For example, the square root of 36 is 6 because 6×6=36.

The general formula for calculating the square root of a number x is:

√x=y

Where:

x is the number whose square root we want to find.

y is the square root of x.

The square root can also be represented in exponential form as:

√x=x^1/2

This formula states that taking the square root of a number is equivalent to raising the number to the power of 1/2.

Example

Let’s find the square root of 25 using the formula:

√25 =25^1/2

√25=5

So, the square root of 25 is 5
