A square root is the number that, when multiplied by itself, gives the original number. The square root of four is two because two x two equals four.

For example, the square root of 4 is 2 because 2*2=4.

### Python Program to calculate the square root using Exponent

# Python Program to calculate the square root using Exponent # we are taking a number from user as input # entered value will be converted to int from string num = int(input("enter a number: ")) # we are using exponent (**) sign sqrt = num ** 0.5 print("square root:", sqrt)

#### Output

```
enter a number: 16
square root: 4.0
```
