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.
