Ответ:
- \(\left(1\frac{1}{6}\right)^9\cdot\left(\frac{6}{7}\right)^{10}=\left(\frac{7}{6}\right)^9\cdot\left(\frac{6}{7}\right)^{10}=\frac{6}{7}\).
- \(5^{14}\cdot0,2^{12}=5^{14}\cdot\left(\frac{1}{5}\right)^{12}=5^2=25\).
- \(\left(-1\frac{1}{3}\right)^5\cdot\left(\frac{3}{4}\right)^8=\left(-\frac{4}{3}\right)^5\cdot\left(\frac{3}{4}\right)^8=-\left(\frac{3}{4}\right)^3=-\frac{27}{64}\).
Ответ: 1) \(\frac{6}{7}\); 2) 25; 3) \(-\frac{27}{64}\).
