    GMAT problems I missed...need help

    First problem really frustrated me, here it is

    ((8^2)(3^3)(2^4))/96^2

    I don't know how to get this answer, I simplified the 8^2 to 2^6 and then combined it with the 2^4 for 2^10 but it didn't give me the right answer b/c the bottom was so hard to figure out.

    That's simply 64 * 27 * 16 / 9216 = 27648 / 9216 = 3

    Try not to complicate things

    We Cannot use a calculator, and the exam is timed, should I have just multiplied it out on paper though?

    ((8^2)(3^3)(2^4))/96^2

    8x8 = 64
    3x3 =9 x 3 = 27
    2x2 = 4 x 2 = 8 x 2 = 16
    64 x 27


    64x27

    27 x 4 = 108
    4 = 108
    8 = 216
    16 = 432
    32 = 864
    64 = 1728

    That is how I'd do it in my head and the same method with the rest of the multiplication
