So what is the common denominator?

You didn't necessarily have to do the last step. And there's more that can be done to simplify it, but I don't think they are asking for that.

I believe it would be 3x2/3, correct? The other parts of the problem require me to solve this for 0 and find where it is undefined. How would I get to that point?

Yes, that is the LCD.

Now solve \(\displaystyle 3x^{2/3} = 0\). It's not hard.
