We're going to simplify 12, x to the negative 3, y to the negative 2, and z to the negative 8, all over 30, x to the negative 6, y to the negative 4, and z to the negative 1.

So to make this a little bit easier, i know if my exponents are negatives, then i can switch their position and make the exponents positive.
00:26
So that's what i'm going to do for every negative exponent.
00:30
I'm going to keep the 12 and 30 where they are, and i'm going to flip, so x over 6 will be on top, and x to the 3 will be on the bottom.
00:40
Y to the 4th on top, y to the 2 on bottom, c to the 1 on top, and z to the 8 on bottom.
00:48
Now i'm going to subtract my exponents and simplify my numbers.
00:55
So 12 and 30 are both divisible by 6...
