Ответ:
1) \(0,5\sqrt{24}-4\sqrt{40}-\sqrt{150}+\sqrt{54}+\sqrt{1000}=\sqrt6-8\sqrt{10}-5\sqrt6+3\sqrt6+10\sqrt{10}=4\sqrt{10}-\sqrt6\).
2) При \(b\ge0\): \(\sqrt{8b}+0,3\sqrt{50b}-3\sqrt{2b}=2\sqrt{2b}+1,5\sqrt{2b}-3\sqrt{2b}=0,5\sqrt{2b}\).
3) \(1,5\sqrt{72}-\sqrt{216}-0,6\sqrt{450}+0,5\sqrt{96}=9\sqrt2-6\sqrt6-9\sqrt2+2\sqrt6=-4\sqrt6\).
Ответ: 1) \(4\sqrt{10}-\sqrt6\); 2) \(0,5\sqrt{2b}\); 3) \(-4\sqrt6\).
