PLEASE Mark as a reference brainlist

Step-by-step explanation:

$( \sqrt{72} + \sqrt{108}) ( \sqrt{ \frac{1}{3} } - \sqrt{ \frac{2}{9} }) \\ (6 \sqrt{2} + 6 \sqrt{3} )( \frac{1}{ \sqrt{3} } - \frac{ \sqrt{2} }{ 3 } ) \\ (6( \sqrt{2} + \sqrt{3} ))( \frac{ \sqrt{3} - \sqrt{2 } }{3} ) \\ \frac{(6( \sqrt{3} + \sqrt{2} ))( \sqrt{3} - \sqrt{2} )}{3} \\ \frac{6( { (\sqrt{3} )}^{2} - { (\sqrt{2} )}^{2}) }{3} \\ 2(3 - 2) \\ 2 \times 1 = 2 \\ ansssssssss$
