Paul, I don't think it should simplify. The following simplifies. poly = p*(p - 1)*b^2 + s^2 prod = Sqrt[poly]*Sqrt[1/poly] Simplify[prod, p > 1 && s > 0 && b \[Element] Reals] 1 Simplify[prod, p > 1 && {s, b} \[Element] Reals] 1 David Park djmp at earthlink.net http://home.earthlink.net/~djmp/ From: paulvonhippel at yahoo [mailto:paulvonhippel at yahoo.com] To: mathgroup at smc.vnet.net I'm having some trouble getting an expression to simplify in an obvious way. (There seems to be a long tradition of users posting to this group with similar troubles.) The expression is poly = p (p - 1) b^2 + s^2 prod = Sqrt [poly] Sqrt[1/poly] Simplify[prod, {0 < p < 1, s > 0, bÏµReals}] which should return one, I think, but doesn't. I'd be grateful for suggestions. Thanks! Paul
