In some previous incarnation, where Sage used Maxima for things like this, your simplification happened. (%i1) 1/sqrt(5); 1 (%o1)  sqrt(5) (%i2) sqrt(5)/5; 1 (%o2)  sqrt(5) Now we use Ginac for basic symbolic stuff. Once in a while we (i.e., Burcin) changes some internal representation, or Ginac does. But in general I think it just goes for positive powers  you may want to read its documentation. In particular, "sqrt" is not a builtin function ("square root (not a GiNaC function, rather an alias for pow(x, numeric(1, 2)))"), so the behavior is analogous to sage: 1/5^(1/3) 1/5*5^(2/3) Naturally, GiNaC is Not a CAS, so perhaps that is one reason for the distinction. You are also right about black arts! So I don't pretend to judge Maxima *or* Ginac on this one. I'm sorry if that doesn't help, but it might give you some background, at least.  kcrisman  To post to this group, send email to [EMAIL PROTECTED] To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sagesupport URL: http://www.sagemath.org
