Ответ:
- \[\frac{15^{\frac{2}{3}}\cdot3^{\frac{7}{3}}}{5^{-\frac{1}{3}}}=\frac{(3\cdot5)^{\frac{2}{3}}\cdot3^{\frac{7}{3}}}{5^{-\frac{1}{3}}}=3^3\cdot5^{\frac{2}{3}+\frac{1}{3}}=27\cdot5=135.\]
- \[\left(\frac45\right)^{-2}-\left(\frac1{27}\right)^{\frac13}+4\cdot379^0=\frac{25}{16}-\frac13+4=\frac{25}{16}+\frac{11}{3}=\frac{251}{48}.\]
- \[\frac{\sqrt[3]{128}+\sqrt[3]{\frac14}}{\sqrt[3]{2}}=\frac{4\sqrt[3]{2}+\frac12\sqrt[3]{2}}{\sqrt[3]{2}}=\frac92.\]
Ответ: 1) 135; 2) \(\frac{251}{48}\); 3) \(\frac92\).
