Have a to the negative fifth, b to the seventh, divided by a to the negative two times b to the negative three.
00:09
So all my negative exponents are going to basically swap spots.
00:15
If they're in the numerator, they're coming down to the denominator.
00:18
And if they're already in the denominator, well, it's one over that.
00:22
So they're going to come up, you multiply by reciprocal, and they come up to the numerator.
00:26
So in the numerator, well, i have.
00:30
Have a b to the positive seventh.
00:32
So that's going to stay in my numerator.
00:34
So i have a b to the seventh, okay, but then i'm also going to have an a squared and a b cubed.
00:42
So i can write those in any order.
00:44
I'm going to write the a first.
00:46
If i'm multiplying, i can multiply in any order i choose.
00:49
So i'm going to have an a squared.
00:52
That's going to come up to the numerator, and then also a b cube, a b to the third power.
00:58
So i'm going to have another b to the third power here...
