The Attempt at a Solution
I have written a proof involving the mean value theorem and derivatives, but there must be a simpler way! I think this should be done purely algebraically. Instructor insists that [itex]\mu[/itex] is an arbitrary non-negative real number, not just a rational or an integer. So to define it we need log, etc. But I believe there is a solution that does not go into this...
