I just probably want to simplify this expression.
00:03
Now to do this, we need to take each fraction on its own, and then we'll go from there.
00:08
Here on the left, we have 18 divided by 9.
00:12
18 divided by 9 is 2.
00:16
We have x squared divided by x.
00:19
And so we subtract our exponents here, 2 minus 1 is 1, so it just gives us x.
00:23
And then y to the 4th over y squared, again subtract your exponents.
00:28
4 minus 2 is 2.
00:29
So we have 2x y to the second.
00:32
It's going to be minus.
00:34
And on this other one, 15 divided by 5 is 3...
