The coefficient of g is approximately 1 and the space is implied multiplication of the inexact 1 times g. You will also sometimes get an approximate zero as a coefficient. expr = (-1. g + r)^4 (r - 1.*g)^4 expr // Rationalize (r - g)^4 Bob Hanlon On Thu, May 14, 2009 at 12:45 PM , Emin Gahramanov wrote: > Hi guys, > sorry for the silly question (I am a Mathematica dummy).
