Arlene claims that the kth root of x can be expressed as x 1/k. which equation below justifies arlene's claim?

(x1k)k=x
(x1k)k=1
(x1k)k=0
(x1k)k=k

The k-th root's inverse function is raising to the k-th power.

So, if we raise the k-th root of some number x to the k-th power, we have applied a function and its inverse to x, and we must get x itself as output:

So, in our case, we have
