Use PowerExpand[ Log[ Exp[x] ] ] or Log[ Exp[x] ] // PowerExpand --------------------- Forwarded message: From: chengli at uab.edu (Cheng Li) To: mathgroup at smc.vnet.net To: mathgroup at smc.vnet.net Dear friends, suppose x is a variable and when I type "Log[Exp[x]]" and then enter, Mathematica gives me "Log[Exp[x]]" back. Could you please tell me how to let Mathematica to return "Log[Exp[x]]" as x? Thank you very much. Cheng Li chengli at uab.edu
