    \[6\sqrt{3}-12\sqrt{2}\]

    27 can be broken down into 9*3, and nine can be broken down into 3*3. It's a square root, so you will look for PAIRS of common terms, and you have three 3's. You can remove two, and put them on the outside. The remaining will stay inside. So 2*3sqrt(3), also 6sqrt(3).

    32, 16*2, and 16=4*4. Remove the fours, and bring them outside, for 3*4sqrt(2), also 12sqrt(2)

    Well just take what I made, (6sqrt(3))(12sqrt(2)), then multiply. 6*12=72, 3*2=6, so your ending answer is 72sqrt(6)
