 Author Comment/Response Sami 09/11/12 8:12pm In Response To 'Re: Re: Re: Re: Re: Re: Collecting terms in an ...'---------Hi guys, Could anyone help me with this please? After trying Bill's suggestion, I tried this one, but didn't work either. prob = expr //. ((_[t_]^2) ..) -> F[t]^2 //. F_[i_]^2 -> F[i]^2*(1/3) I have attached the nb image. Just to summarize the question: What I have: expr=Exp[a Fx[1]^2+a Fy[1]^2+a Fz[1]^2+b Fx[2]^2+b Fy[2]^2+b Fz[2]^2+c Fx[3]^2+c Fy[3]^2+c Fz[3]^2]; What I need: prob= Exp[ a*F[1]^2 + b*F[2]^2 + c*F[3]^2 ] Thanks indeed.
