1) $$3^{-2} + (\frac{18}{5})^{-1} = \frac{1}{3^2} + \frac{5}{18} = \frac{1}{9} + \frac{5}{18} = \frac{2}{18} + \frac{5}{18} = \frac{7}{18}$$
Ответ: $$\frac{7}{18}$$
2) $$\frac{13^{-8} \cdot 13^{-7}}{13^{-14}} = \frac{13^{-8-7}}{13^{-14}} = \frac{13^{-15}}{13^{-14}} = 13^{-15 - (-14)} = 13^{-15 + 14} = 13^{-1} = \frac{1}{13}$$
Ответ: $$\frac{1}{13}$$
