zalgotext, 1 year ago (edited 1 year ago) 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.
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) =
