# Find square root of a number using exponential operation

Hello everyone, welcome back! Here we learn about a python program which finds the square root of a given number. We find the square-root of a number using exponential operations.

Here I calculate the square-root by finding the power of the number with 0.5, as you all know that square-root of a number is equal to its power by half. So now I use this way to calculate the result.

One can also find the square-root of a number using a built-in function called `sqrt()`, Look at my other post here which shows the same.

#### Square Root – Code Visualization

To find the square-root of a given number

#### Approach :

• Read input number for which the square root is to be calculated using `input()` or`raw_input()`.
• Use exponential operation ** to that number with 0.5
• The obtained result of the above operation is required square-root.
• Print the result.
