What a bunch of literal-minded answers. Hacking on
syntax or un-simplified forms is not going to get
you anywhere but solving this one problem.
You might as well tell Mike that the solution is the
function foo[q_]:=e^2;
then foo[(a/b)^2] becomes e^2.
Here's a solution more in the spirit of solving the
problem, which is to find occurrence of a/b mathematically.
Try
Last[PolynomialReduce[(a/b)^2, {e - a/b}, {a}]]
