Python math module

0 votes
I have been using the built-in functions of Exponentiation and logarithms module in Python. But everytime I get the following error:

NameError: name 'sqrt' is not defined

I have tried using math.sqrt(4),sqrt(4) and sqrt(4.0) as substitutes but even these didn't work. Can anyone tell me what is wrong?

Try the following:

import math
