Answer 2

➡HERE IS YOUR ANSWER⬇

$12 \sqrt{18} - 6 \sqrt{20} - 3 \sqrt{50} + 8 \sqrt{45} \\ \\ = 12 \sqrt{3.3.2} - 6 \sqrt{5.2.2} - 3 \sqrt{5.5.2} + 8 \sqrt{3.3.5} \\ \\ = 12.3 \sqrt{2} - 6.2 \sqrt{5} - 3.5 \sqrt{2} + 8.3 \sqrt{5} \\ \\ = 36 \sqrt{2} - 12 \sqrt{5} - 15 \sqrt{2} + 24 \sqrt{5} \\ \\ = (36 - 15) \sqrt{2} + (24 - 12) \sqrt{5} \\ \\ = 21 \sqrt{2} + 12 \sqrt{5} \\ \\ = 3(7 \sqrt{2} + 4 \sqrt{5} )$
