    The first rule is just simple division:

    (2x2x2x2) / (2x2) =

    (2/2) * (2/2) * 2 * 2=

    1 * 1 * 2 * 2 =

    2 * 2 =

    4

    Writing in terms of powers:

    (2^4) / (2^2) =

    (2^(4-2)) =

    (2^2) =

    4

    The two bottom 2’s “cancel out” (really they just divide into one another to make 1’s) two of the top 2’s and you’re left with two top twos.
