Ответ:
а) \(\sqrt[4]{\frac{16}{81}}+\sqrt[3]{-\frac18}=\frac23-\frac12=\frac16\).
б) \(\sqrt[5]{0.00032}+\sqrt[3]{-0.008}=0.2-0.2=0\).
в) \(1.5\sqrt[6]{\frac1{64}}-\sqrt[4]{\frac{81}{625}}=1.5\cdot\frac12-\frac35=0.75-0.6=0.15\).
а) \(\sqrt[7]{\frac{128}{2187}}-\sqrt[4]{\frac{81}{625}}=\frac23-\frac35=\frac1{15}\).
б) \(\sqrt[3]{0.216}-\sqrt[5]{-0.01024}=0.6-(-0.4)=1\).
в) \(\sqrt[5]{7\frac{19}{32}}+\sqrt{12.25}=\sqrt[5]{\frac{243}{32}}+3.5=1.5+3.5=5\).
