Homework Help: Evaluate in terms of powers of primes

  1. Jun 4, 2012 #1
    33 x 42
    __________________________ =
    2 x 3-3 x 16

    33-(-3) = 6
    16 = 42 .... 42-2 = 0

    so.. 36 x 2 <-- answer I guess Im not sure

    How did the 2 in the denominator come up in the numerator??

    The rest is correct, though. :smile:

    so the answer is 3^6 / 2 ??

    Im sorry have another question is kinda the similar .
    Simplify the following expressions:

    23x 4x or 22x
    _________________________________________ =
    16x or 24x

    23x+2x = 5x = 25x / 24x = 2x
