2^5 * 2^2 = 128

extract the "whole" fifth root

fifth root (2^5 * 2^2) = 2 [fifth root(2^2)]

7 / fifthroot(128) = 7 / {2 [fifth root(2^2)]}

to remove radical from the denominator
multiply by ___ [fifth root(2^3)] / [fifth root(2^3)]

{7 [fifth root(2^3)]} / {2 [fifth root(2^2)] [fifth root(2^3)]}

{7 [fifth root(2^3)]} / {2 [fifth root(2^5]}

{7 [fifth root(2^3)]} / 4
