Practice problems. I am studying for an upcoming test.?

I want to make sure I understand how to solve this problem. Here is what I have so far.

3 sqrt2/2 sqrt6-sqrt10

From here I know that I have to multiply by the top and bottom of the problem again on the right side of the problem

So now I have 3 sqrt2/2 sqrt6-10*3 sqrt2/2 sqrt6-10

Will I have 9 sqrt2 now? How do I multiply the bottom? Will the denominator be 2?
