I say 9 as well. With PEMDAS, it's what's inside the parenthesis. As others have said, when the one number is in the parenthesis and the other is outside, it can simply be rewritten with a multiplication symbole.
2(3) = 2 * 3, and once you rewrite it that way, PEMDAS takes over and you divide 6/2 first then multiply by 3.
Also just punched it into my TI-83 and got 9. I trust that thing with my life...well at least when it comes to math.
