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

#### Task :

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.

#### Program :

1 2 3 4 |
num = float(input('Enter a number: ')) sqrt = num ** 0.5 print('The square root of %0.3f is %0.3f' % (num, sqrt)) |

#### Output :
