Homework Help: Question about exponents

  1. Sep 25, 2008 #1
    1. The problem statement, all variables and given/known data
    How do you solve this probem for E:

    E + sqrt(aE) = b

    where 'a' and 'b' are constants.

    I don't recall how to handle the exponents where you have E + aE^1/2 = b and solve for E.

    Rewrite it as sqrt(aE)=b-E. Now square both sides. It's a quadratic equation in E.
