Quick logic question

  1. Sep 20, 2010 #1
    what is another way to form (a+b)^c to another simple expression?
    like for example a^c+b^c doesnt work because its not eqivalent to (a+b)^c
    (without using squareroot)

    im know of no way that is simpler. just look at the example of (a+b)^100.

    how simple is that? or just try to simplify (a+b)^3.

    I occasionally find it useful to write it as a^c * (1 + b/a)^c -- of course only when working over the reals.

    it doesn't have to be simpler, just not so complicated. thanks CRGreathouse, that helps,
