Hi I'm wondering how to tell mathematica that I want terms like Sqrt[x^2+x^4] to be x*Sqrt[1+x^2]. I have an expression with a few terms like this in it so manually inserting a PowerExpand[Sqrt[Expand[x^2+x^4]] is no good to me. I've tried a general PowerExpand and Simplify with a Im[x]==0 around the whole expression but with no luck. Does anybody know how to do this? Thanks, Bill -- William R.
