Ответ:
- \(64^{1/2}=\sqrt{64}=8\).
- \(27^{1/3}=\sqrt[3]{27}=3\).
- \(8^{2/3}=\sqrt[3]{8^2}=\sqrt[3]{64}=4\).
- \(81^{3/4}=\sqrt[4]{81^3}=(\sqrt[4]{81})^3=3^3=27\).
- \(16^{-0,75}=16^{-3/4}=\frac{1}{\sqrt[4]{16^3}}=\frac{1}{2^3}=\frac18\).
- \(9^{-1,5}=9^{-3/2}=\frac{1}{\sqrt{9^3}}=\frac{1}{3^3}=\frac1{27}\).
Ответ: 1) 8; 2) 3; 3) 4; 4) 27; 5) \(\frac18\); 6) \(\frac1{27}\).
