Homework Help: Simple algebra-calculus question

  1. Apr 4, 2010 #1
    1. The problem statement, all variables and given/known data, and relevant equations

    How is A6 arrived at and *how* did they get the "Q" in A6?


    2. Relevant equations

    See above

    3. The attempt at a solution

    Objective: Rid A1 of L. They simply substituted "C" in A2 into A1. But how did they get rid of the L? I don't quite get the algebraic manipulation...please help

    What I specifically do not understand is how the exponents, alpha and beta, have been manipulated to be ratios. The only way I think you can do that is by using logarithms, but I do not quite know how.

    Anyone have any ideas?
