Collecting Non-integer ExponentsQ: I want to deal with an expression containing non-integer powers of x, such as
However, when I try
it appears that Collect only works with integers. Is there a way to deal with this situation? A: Daniel Lichtblau (danl@wolfram.com) answers: One way to perform the Collect is to allow a pattern variable for the exponent. This will in effect create a separate "variable" for each distinct power, and this suffices to do what you want in this particular example.
