Given the following two equivalent inverse functions, why does one simplify (using inverse functions that are acceptable to me) and the other doesn't? Is there an assumption or setting I can give which will force these to use inverse functions and simplify properly? $Assumptions = A > 0 && k < 1 && k > 0; InverseFunction[(#1 A^k (#1)^k) &] // FullSimplify InverseFunction[(#1 (A #1)^k) &] // FullSimplify Thanks, Jesse
