\[\left(\frac{2}{3}\right)^8 \cdot \left(\frac{3}{8}\right)^6 = \frac{2^8}{3^8} \cdot \frac{3^6}{8^6} = \frac{2^8 \cdot 3^6}{3^8 \cdot (2^3)^6} = \frac{2^8 \cdot 3^6}{3^8 \cdot 2^{18}} = \frac{3^{6-8}}{2^{18-8}} = \frac{3^{-2}}{2^{10}} = \frac{1}{3^2 \cdot 2^{10}} = \frac{1}{9 \cdot 1024} = \frac{1}{9216}\]
Ответ: \(\frac{1}{9216}\)
\[\frac{3^{16} \cdot 2^{10}}{54^5} = \frac{3^{16} \cdot 2^{10}}{(2 \cdot 3^3)^5} = \frac{3^{16} \cdot 2^{10}}{2^5 \cdot 3^{15}} = 3^{16-15} \cdot 2^{10-5} = 3 \cdot 2^5 = 3 \cdot 32 = 96\]
