PowerExpand

• Example: PowerExpand[Sqrt[x y]].

• PowerExpand converts (a b)^c to a^c b^c, whatever the form of c is.

• PowerExpand also converts (a^b)^c to a^(b c), whatever the form of c is.

• The transformations made by PowerExpand are correct in general only if c is an integer or a and b are positive real numbers.

• PowerExpand converts Log[a^b] to b Log[a].

• See Section 1.4.5 and Section 3.3.1.

• See also: Expand, Distribute, ComplexExpand, FullSimplify, FunctionExpand, Refine.
