Question

Answer 1

\(6,=5\sqrt{2}-4\sqrt{2}+9\sqrt{3}=\sqrt{2}+9\sqrt{3}\\ 7,=4\sqrt{3}+3\sqrt{3}-8\sqrt{3}=-\sqrt{3}\\ 8,=2\sqrt{5}-3\sqrt{5}+9\sqrt{2}+6\sqrt{2}=15\sqrt{2}-\sqrt{5}\\ 9,=3\sqrt{3}+4\sqrt{3}-2\sqrt{3}=5\sqrt{3}\\ 10,=3\sqrt{5}-2\sqrt{5}+3\sqrt{2}-3\sqrt{2}=\sqrt{5}\)

Answer 2

6: \(=5\sqrt{2}-4\sqrt{2}+9\sqrt{3}=9\sqrt{3}+\sqrt{2}\)
