Before we try any fancy importing, let's see what Python already knows about square roots. On line 3 in the editor, ask Python to

print sqrt(25)

which we would expect to equal five.

```
Replace this line with your code.
# Ask Python to print sqrt(25) on line 3.
def sqrt(num):
num1 = num**0.5
print 'sqrt(%d) = %d' %(num,num1)
sqrt(25)
```
