00:01
So in a situation like this, we have to use our exponent rules.
00:04
And the main one here is if we have x to a over x to the b, we're going to do x to the a minus b.
00:10
So we're going to be subtracting some exponents here.
00:13
The very first one is that negative 9 .8 with the other a will be minus, and then we have that negative 2 over 3.
00:20
So the best bet here, this is a double negative.
00:23
So we're going to add that.
00:24
But we've got to get a common denominator.
00:26
So i'm going to multiply the first one by 3.
00:27
So i have negative 27 over 24.
00:30
And i'm going to add on to it.
00:31
I'm going to multiply the right by 8.
00:34
So it will be 16 over 24.
00:36
So in the end here, when we combine, we're just going to be combining negative 27 plus 16 for our piece there.
00:44
And we get negative 11 over 24.
00:47
So for our exponent here, it's going to be a negative 11 over 24.
00:53
So then same thing with the b...
