We want to rationalize the numerator for the expression, cube root of x squared y over 2x.
00:08
Remember that rationalize means we want to remove any traces of a root function, such a square rate, cube root, or eighth root.
00:14
So we want to get rid of the cube root function in this numerator just in the final solution.
00:20
To simplify an expression like this, we also need to know exponent root rules.
00:24
The seven listed here, a through g are the most important.

We don't need all of them for this one problem, but they make it a lot easier to solve similar problems, so should be noted whenever you're doing similar problems in a query test.

Also worth noting is rule a, which connects the root and exponential functions...
