What is the ordered pair?

Question

If z=64, then the value of z^(1/6) when k=5 is? [Answer must be in (x,y) form]

Answer 1

If z = 64, then it is easy to find z^1/6 by substitution: z^1/6 = 64^1/6 = 2. I don't understand why k = 5 is relevant to the problem or why the answer should be in (x,y) form. Are you sure that you copied the problem correctly?
