Answer 2

AnSwEr :-

$= 12 \sqrt{18} - 6 \sqrt{20} - \sqrt{3} \sqrt{50} + 8 \sqrt{45} \\ \\ = 12 \sqrt{2 \times 3 \times 3} - 6 \sqrt{2 \times 2 \times 5} - \sqrt{150} + 8 \sqrt{3 \times 3 \times 5} \\ \\ = 36 \sqrt{2} - 12 \sqrt{5} - \sqrt{2 \times 3 \times 5 \times 5} + 24 \sqrt{5} \\ \\ = 36 \sqrt{2} - 12 \sqrt{5} - 5 \sqrt{6} + 24 \sqrt{5} \\ \\ = 36 \sqrt{2} - 12 \sqrt{5} + 24 \sqrt{5} - 5 \sqrt{6} \\ \\ = 36 \sqrt{2} + 12 \sqrt{5} - 5 \sqrt{6}$
