I'm trying to use the Collect[] function to collect terms in the exponent of an expression, which Mathematica has output in the form term = Power[E,exponent]. It seemed to me (rightly or wrongly) that the easiest way to do this was to take the natural log of my variable "term" thereby returning "exponent". i.e. temp=Log[term] Then, I could: temp1=Collect[term, collection_variable] temp2=E[temp1] and temp2 would equal term but my exponent would be grouped the way I wanted. Instead, it appears that temp is returned unevaluated. The code is shown below. In[109]:= term=Power[E,exponent] temp=Log[term] Out[109]= exponent E Out[110]= exponent Log[E ] My question is twofold, (a) why won't mathematica output exponent when I take natural log of E^exponent and (b) is there a better way to Collect terms in an exponent. Thanks to anyone who can help. Paul Hines
