24, let's simplify this rational expression.
00:08
And so all you have to be able to do here is reduce a fraction and do a little subtraction with exponents, right? remember that v or any variable by itself actually has an exponent of one.
00:21
And if you watched any of the previous videos of this type of problem, you know that you're going to have to do a little subtraction of exponents.
00:28
But the exponent's got to stay positive.
00:30
So wherever the exponent is bigger, that's where the very, is going to stay.
00:35
Again, i like to divide these up.
00:38
I'm just going to pair everything together.
00:41
I'm going to put the 36 with the 27.
00:43
I'm going to put the vs together and i'm going to put the ws together.
00:47
Simplify them and then multiply them back together.
00:50
So like so.
00:51
36 over 27 times v to the third over v to the first times w squared over w to the third.
01:03
So the first one we reduce.
01:05
And then here we're going to subtract one up...
