Homework Help: Rearranging an Energy Decay Equation

  1. Feb 11, 2010 #1
    Hi, I'm having trouble rearranging this equation, solving for E(t):

    E(t) = Eo*e^(-t/T)

    My attempt:

    ln E(t) = Eo * (-t/T) and now I'm stuck.

    Any help would be appreciated!

    The logarithm of the right side is incorrect.

    What is the logarithm of a product?
    What is the logarithm of e raised to some power?

    Please review the answers to these two questions.
