Any degree element(root) from any number

Question

Did exist better, more precise method to calculate any degree element/root from any number. I've tried this:

y = lambda x: pow(x[0], 1/x[1])
print(y((64,3)))

but this use rounds 1/3 and it cause low precision

Answer 1

@Jay Matthews -> its correct only when we expect result is integer. Your solution doesn't work correctly for most options, example:

print(int(2**(1/2)))
print(2**(1/2))

or

print(int(64**(1/3)))
print(64**(1/3))

Only way is to use round function and set precise?

print(round(64**(1/3),3))
