Find the Nth root in R

Question

How do we find the Nth root in R?

4^2 = sqrt(16)

But what is the code snippet for the opposite transformation of;

4^7 = ???

Simple

sqrt(4) == 4^(1/2)
# 7th root of 4
4^(1/7)

In calculus, roots are treated as special cases of exponentiation, where the exponent is a fraction:

$\sqrt[n]{x}}=x^{1/n}$
