Re: A little simplification problem

Thank you!  In fact the rule

expandPowers := rule x^(n+k) == x*x^(n+k-1)

also seems to work well.  But why does Axiom not automatically apply this
rule for simplification of expressions involving powers, as other CAS's
(Maple, Maxima, Mathematica) do?

Thanks again,
Alasdair
