    [SOLVED] Logs

    hi
    Log4(32) - log9(27)

    my attempt
    log4(2^5)-log9(3^3)
    5log4(2)- 3log9(3)

    what do i do from here, does something cancel out ?

    cheers

    \log_4{2} = \frac{1}{2} because 4^{\frac{1}{2}} = 2. Similarly, \log_9{3} = \frac{1}{2}.

    Can you take it from here?
