Ответ:

  1. \(0.6\sqrt{36}=0.6\cdot6=3.6\).
  2. \(-2.5\sqrt{25}=-2.5\cdot5=-12.5\).
  3. \(\sqrt{0.49}+\sqrt{0.16}=0.7+0.4=1.1\).
  4. \(\sqrt{0.64}-\sqrt{0.04}=0.8-0.2=0.6\).
  5. \(-\sqrt{0.0036}+\sqrt{0.0025}=-0.06+0.05=-0.01\).
  6. \(\sqrt{0.01}-\sqrt{0.0001}=0.1-0.01=0.09\).
  7. \(\frac{1}{3}\sqrt{0.81}-1=\frac{1}{3}\cdot0.9-1=0.3-1=-0.7\).
  8. \(4-10\sqrt{0.01}=4-10\cdot0.1=3\).
