Упростите выражения: г) √54 − √24 + √150; д) 3√2 + √32 − √200; е) 2√72 − √50 − 2√8.

1. \(\sqrt{54}=3\sqrt{6}\), \(\sqrt{24}=2\sqrt{6}\), \(\sqrt{150}=5\sqrt{6}\).

   \(3\sqrt{6}-2\sqrt{6}+5\sqrt{6}=6\sqrt{6}\).

2. \(\sqrt{32}=4\sqrt{2}\), \(\sqrt{200}=10\sqrt{2}\).

   \(3\sqrt{2}+4\sqrt{2}-10\sqrt{2}=-3\sqrt{2}\).

3. \(\sqrt{72}=6\sqrt{2}\), \(\sqrt{50}=5\sqrt{2}\), \(\sqrt{8}=2\sqrt{2}\).

   \(2\cdot6\sqrt{2}-5\sqrt{2}-2\cdot2\sqrt{2}=3\sqrt{2}\).

Ответ: г) \(6\sqrt{6}\); д) \(-3\sqrt{2}\); е) \(3\sqrt{2}\).
