    b^4

    does this simplify to 12b^4 or 12b^8?

    4b^5 * 3b^7
    -------------
    b^4

    simplify top line:

    12b^12
    -------
    b^4

    giving answer: 12b^8

    (as 12/1 = 12, and we deduct 4 from 12 to get the new power of 8; as we r dividing)

    (4bbbbb x 3bbbbbbb) / bbbb

    = 12bbbbbbbbbbbb / bbbb

    cancelling

    = 12bbbbbbbb

    = 12b^8
