Ответ:
- \(243^{0,4}=(3^5)^{\frac{2}{5}}=3^2=9\).
- \(\left(\frac{64^4}{3^8}\right)^{-\frac{1}{8}}=\left(\frac{2^{24}}{3^8}\right)^{-\frac{1}{8}}=\left(\left(\frac{8}{3}\right)^8\right)^{-\frac{1}{8}}=\frac{3}{8}\).
- \(16^{\frac{5}{4}}=(2^4)^{\frac{5}{4}}=2^5=32\).
- \(\left(\frac{27^3}{125^6}\right)^{\frac{2}{9}}=\left(\frac{3^9}{5^{18}}\right)^{\frac{2}{9}}=\left(\left(\frac{3}{25}\right)^9\right)^{\frac{2}{9}}=\frac{9}{625}\).
