For problems like these, we want to get rid of these fractions within a fractions.
00:04
So what we're going to do is multiply by the least common denominator.
00:07
Between x and x to the fourth, the least common denominator between those would be x to the fourth.
00:13
So i know i'm going to have to multiply the numerator by x to the fourth.
00:16
Between y squared and y, we're going to be using y squared.
00:19
So this is what we're going to multiply by, and what that will do is eliminate all of these fractions.
00:24
When we do it, we're going to distribute through to each of those.
00:26
For example, when i go to the 3, it'll be 3x to the 4th, y squared, all over x.
00:32
Well, one of these xs are going to cancel out, and this will come down to 3...
