Simplification of Log/Exponent Expression

  1. Aug 30, 2009 #1
    1. The problem statement, all variables and given/known data

    Simplify the following:

    [log_3(2^x) * 3^(2x)]/e^(2lnx)

    3. The attempt at a solution

    e^(2lnx) = x^2
    Log_3(2^x) = xlog_3(2)


    = 3^(2x)*x*log_3(2) / x^2
    = [3^(2x)/x] * log_3(2)

    Am I missing anything here? I don't seem to find anyway to continue simplification, although the 3^2x seems like a weird choice if I cannot somehow use log_3(2) with it.

    Hi moo5003! :smile:
