Homework Help: Simplifying equation

  1. Oct 17, 2007 #1
    I am trying to solve for the variable lambda in terms of A. After multiplying the denominator term over to the other side, how do I go on from there? I don't know how to get rid of the exponential terms.

    Thanks on advance.

    You can take the log of both sides

    Or, you can use logical reasoning to conclude that if the bases on each side are equal, then...?

    "the bases on each side are equal" and exponential is a one-to-one function!

    You're equation looks correct so far, but you can reduce it to lamba in terms of A.

    Hint: Expand the binomial on the RHS.
