Ответ:

  1. \(\sqrt{175}=\sqrt{25\cdot7}=5\sqrt7\).
  2. \(\sqrt{128}=\sqrt{64\cdot2}=8\sqrt2\).
  3. \(\sqrt{700}=\sqrt{100\cdot7}=10\sqrt7\).
  4. \(\sqrt{180}=\sqrt{36\cdot5}=6\sqrt5\).
  5. \(\sqrt{3\cdot4.41}=\sqrt{3\cdot2.1^2}=2.1\sqrt3\).
  6. \(\sqrt{0.0128}=\sqrt{0.0064\cdot2}=0.08\sqrt2\).

Ответ: 1) \(5\sqrt7\); 2) \(8\sqrt2\); 3) \(10\sqrt7\); 4) \(6\sqrt5\); 5) \(2,1\sqrt3\); 6) \(0,08\sqrt2\).
