Ответ:

  1. \(\sqrt[3]{-125}+\frac18\sqrt[6]{64}=-5+\frac18\cdot2=-5+\frac14=-\frac{19}{4}\).
  2. \(\sqrt[5]{32}-0{,}5\sqrt[3]{-216}=2-0{,}5\cdot(-6)=2+3=5\).
  3. \(-\frac13\sqrt[4]{81}+\sqrt[4]{625}=-\frac13\cdot3+5=-1+5=4\).
  4. \(\sqrt[3]{-1000}-\frac14\sqrt[4]{256}=-10-\frac14\cdot4=-10-1=-11\).
  5. \(5\sqrt{\frac1{243}}+\sqrt[3]{-0{,}001}-\sqrt[4]{0{,}0016}=5\cdot\frac1{9\sqrt3}-0{,}1-0{,}2=\frac{5\sqrt3}{27}-0{,}3\).

Ответ: 1) \(-\frac{19}{4}\); 2) \(5\); 3) \(4\); 4) \(-11\); 5) \(\frac{5\sqrt3}{27}-0{,}3\).
