1. \(\left(\frac{-18}{5}\right)^{-1}=\left(-\frac{5}{18}\right)^{1}=- \frac{5^{1}}{18^{1}}=- \frac{5}{18}\)
2. \(\left(\frac{-5}{3}\right)^{-4}=\left(-\frac{3}{5}\right)^{4}= \frac{3^{4}}{5^{4}}=\ldots \text{ZRM}\)
3. \(\left(\frac{-5}{3}\right)^{-1}=\left(-\frac{3}{5}\right)^{1}=- \frac{3^{1}}{5^{1}}=- \frac{3}{5}\)
4. \(\left(\frac{-9}{5}\right)^{-3}=\left(-\frac{5}{9}\right)^{3}=- \frac{5^{3}}{9^{3}}=\ldots \text{ZRM}\)
5. \(\left(\frac{-8}{9}\right)^{-2}=\left(-\frac{9}{8}\right)^{2}= \frac{9^{2}}{8^{2}}= \frac{81}{64}\)
6. \(-\left(\frac{-16}{7}\right)^{-1}=-\left(-\frac{7}{16}\right)^{1}= \frac{7^{1}}{16^{1}}= \frac{7}{16}\)
7. \(\left(\frac{-18}{3}\right)^{-2}=\left(-\frac{3}{18}\right)^{2}= \frac{3^{2}}{18^{2}}= \frac{9}{324}\)
8. \(\left(\frac{-20}{9}\right)^{-1}=\left(-\frac{9}{20}\right)^{1}=- \frac{9^{1}}{20^{1}}=- \frac{9}{20}\)
9. \(\left(\frac{-18}{7}\right)^{-4}=\left(-\frac{7}{18}\right)^{4}= \frac{7^{4}}{18^{4}}=\ldots \text{ZRM}\)
10. \(\left(\frac{-14}{3}\right)^{-1}=\left(-\frac{3}{14}\right)^{1}=- \frac{3^{1}}{14^{1}}=- \frac{3}{14}\)
11. \(-\left(\frac{-11}{6}\right)^{-3}=-\left(-\frac{6}{11}\right)^{3}= \frac{6^{3}}{11^{3}}=\ldots \text{ZRM}\)
12. \(\left(\frac{-8}{9}\right)^{-3}=\left(-\frac{9}{8}\right)^{3}=- \frac{9^{3}}{8^{3}}=\ldots \text{ZRM}\)
