I am glad to see that there is a way to convince Mathematica the two expressions are equal. Or, if not equal, at least to get beyond the real vs rational. FYI, I had used ^.5 in one of my definitions; once I changed that to ^(1/2) the two answers were in the form. Vale, Rip -- Multiplication is not commutative before breakfast. Richard I.
