Answer 2

1/ \(=\sqrt{3}-4\sqrt{3}+9\sqrt{3}-16\sqrt{3}+25\sqrt{3}=15\sqrt{3}\)

2/ \(=5\sqrt{7}-8\sqrt{7}-9\sqrt{7}-4\sqrt{7}+\sqrt{7}=-15\sqrt{7}\)

3/ \(=15\sqrt{3}-6\sqrt{2}-20\sqrt{3}+5\sqrt{3}=6\sqrt{2}\)

4/ \(=\left(2\sqrt{3}-2\sqrt{3}+6\sqrt{3}\right):3\sqrt{3}=2\)

5/ \(=\left(4\sqrt{2}-6\sqrt{2}-15\sqrt{2}\right)\sqrt{2}-20+1=-53\)
