PowerExpand

  • PowerExpand[ expr ] expands all powers of products and powers.
  • 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 The Mathematica Book on the web:Section 1.4.5 and Section 3.3.1.
  • See also: Expand, ComplexExpand, FullSimplify.
