Ответ:

  1. а) \(10\sqrt{3}-4\cdot4\sqrt{3}-5\sqrt{3}=(10-16-5)\sqrt{3}=-11\sqrt{3}\).
  2. б) \((5\sqrt{2}-3\sqrt{2})\sqrt{2}=2\sqrt{2}\cdot\sqrt{2}=4\).
  3. в) \((3-\sqrt{2})^2=9-6\sqrt{2}+2=11-6\sqrt{2}\).
  4. г) \(2\sqrt{2}+5\sqrt{2}-7\sqrt{2}=0\).
  5. д) \((3\sqrt{5}-2\sqrt{5})\sqrt{5}=\sqrt{5}\cdot\sqrt{5}=5\).
  6. е) \((\sqrt{5}+\sqrt{2})^2=5+2\sqrt{10}+2=7+2\sqrt{10}\).
