Precalculus Properties of Logarithmic Functions Logarithm-- Inverse of an Exponential Function 1 Answer KillerBunny Oct 5, 2015 #x= e^y# Explanation: Simply consider the fact that, if #log(x)=y#, than also #e^{log(x)}=e^y# must hold. Now use the fact that the exponential function #e^x# is the inverse of the logarithmic function #log(x)#, which means that #e^{log(x)}=x#, and thus the solution.
