im just checking to make sure i did my problems right before tomorrow i had to simplify 6 sq.root2 devided by sq.root3. I came up with 2 sq.root6 is this done right?

I'm going to assume your problem is this:

6√2 / √3

Rationalize the denominator by multiplying the equivalent of 1, which would be: √3 / √3

When you do this, you will have:
6√6 / 3
which reduces to:
2√6

Your answer is correct! Good job!
