    Smile Equations

    Hi,
    I've tried to solve this equation, but I got the wrong answer.
    Could anymore kindly explain to me how to solve it?

    Find the exact solution of the equation 9^2x = 27^(i-x).

    Thanks,
    Amine.

    9 = 3^2 and 27 = 3^3

    So you have

    3^{2(2x)} = 3^{3(i - x)}.
