а) \( 4^{-2} \)
\( 4^{-2} = \frac{1}{4^2} = \frac{1}{16} \)
б) \( (-3)^{-3} \)
\( (-3)^{-3} = \frac{1}{(-3)^3} = \frac{1}{-27} = -\frac{1}{27} \)
в) \( (-1)^{-9} \)
\( (-1)^{-9} = \frac{1}{(-1)^9} = \frac{1}{-1} = -1 \)
г) \( \left( \frac{1}{7} \right)^{-2} \)
\( \left( \frac{1}{7} \right)^{-2} = \left( \frac{7}{1} \right)^{2} = 7^2 = 49 \)
ж) \( \left( 1 \frac{1}{2} \right)^{-5} \)
\( 1 \frac{1}{2} = \frac{3}{2} \)
\( \left( \frac{3}{2} \right)^{-5} = \left( \frac{2}{3} \right)^{5} = \frac{2^5}{3^5} = \frac{32}{243} \)
и) \( 0.01^{-2} \)
\( 0.01 = \frac{1}{100} \)
\( \left( \frac{1}{100} \right)^{-2} = \left( \frac{100}{1} \right)^{2} = 100^2 = 10000 \)
к) \( 1.125^{-1} \)
\( 1.125 = 1 \frac{125}{1000} = 1 \frac{1}{8} = \frac{9}{8} \)
\( \left( \frac{9}{8} \right)^{-1} = \frac{8}{9} \)
Ответ: а) \( \frac{1}{16} \); б) \( -\frac{1}{27} \); в) -1; г) 49; ж) \( \frac{32}{243} \); и) 10000; к) \( \frac{8}{9} \).
