How do we square root in python

Question

I can’t seem to square root with the sqrt function in the SoloLearn idle
What should I do?
I tried import math
I tried sqrt()
I tried loads of things

Answer 1

Aside from using sqrt() function from math module, you can use exponent operation (**). And use 1/2 or 0.5 as the exponent.

81 ** (1/2)
>> 9.0

You can also perform a cube root by using 1/3.

81 ** (1/3)
>> 3.0

Answer 2

the code below works for me.

import math

x=math.sqrt(9)
print(x)
# ouput 3

Answer 3

from math import sqrt

print(sqrt(81))
