# Python Program to Find the Square Root of number

In this post, we will see how to find square root of a number in python.

There are many ways to do it but I will discuss below two

- Using ** operator
- Using math library

## Using ** operator

As you might know, you can use ** to find power of number in python. If you want square root, you can simply use 0.5 with number.

```
num=25
sqrtRoot=num**0.5
print(sqrtRoot)
```

**Output**

5.0

But above approach will work only for positive numbers, you need to use other ways for negative numbers.

## Using math library

you can import math package and use math.sqrt to find square root of a number.

```
import math
num=25
sqrtRoot=math.sqrt(num)
print(sqrtRoot)
```

**Output**

5.0

That’s all about finding square root of a number in pyhton.
