Simplfying inside Sqrt


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
