nth root of
x^(1/n), so you can do
9**(1/2) to find the 2nd root of 9, for example. In general, you can compute the nth root of x as:
Note: In Python 2, you had to do
1.0/n so that the result would be a
float rather than an
int. For more details, see Why does Python give the “wrong” answer for square root?
