Subject: [mg18229]  [mg18211] Canceling square roots with Simplify




Hello,

Try typing in the following in a new session of Mathematica (I'm currently
running ver 3.0 under WinNT).

Simplify[ Sqrt[b^2]*Sqrt[1/b^2] ]

It seems like the b's should cancel, and I should get 1. Why don't I? Is
there any workaround?

Thanks very much

Everett G. Farr
