1. \(\left(\frac{-2}{7}\right)^{-3}=\left(-\frac{7}{2}\right)^{3}=- \frac{7^{3}}{2^{3}}=\ldots \text{ZRM}\)
2. \(\left(\frac{-9}{5}\right)^{-2}=\left(-\frac{5}{9}\right)^{2}= \frac{5^{2}}{9^{2}}= \frac{25}{81}\)
3. \(-\left(\frac{-12}{5}\right)^{-1}=-\left(-\frac{5}{12}\right)^{1}= \frac{5^{1}}{12^{1}}= \frac{5}{12}\)
4. \(-\left(\frac{-18}{5}\right)^{-1}=-\left(-\frac{5}{18}\right)^{1}= \frac{5^{1}}{18^{1}}= \frac{5}{18}\)
5. \(\left(\frac{-8}{9}\right)^{-3}=\left(-\frac{9}{8}\right)^{3}=- \frac{9^{3}}{8^{3}}=\ldots \text{ZRM}\)
6. \(-\left(\frac{-9}{5}\right)^{-4}=-\left(-\frac{5}{9}\right)^{4}=- \frac{5^{4}}{9^{4}}=\ldots \text{ZRM}\)
7. \(\left(\frac{-18}{5}\right)^{-3}=\left(-\frac{5}{18}\right)^{3}=- \frac{5^{3}}{18^{3}}=\ldots \text{ZRM}\)
8. \(\left(\frac{-15}{8}\right)^{-1}=\left(-\frac{8}{15}\right)^{1}=- \frac{8^{1}}{15^{1}}=- \frac{8}{15}\)
9. \(\left(\frac{-19}{4}\right)^{-1}=\left(-\frac{4}{19}\right)^{1}=- \frac{4^{1}}{19^{1}}=- \frac{4}{19}\)
10. \(-\left(\frac{-13}{7}\right)^{-3}=-\left(-\frac{7}{13}\right)^{3}= \frac{7^{3}}{13^{3}}=\ldots \text{ZRM}\)
11. \(-\left(\frac{-2}{9}\right)^{-4}=-\left(-\frac{9}{2}\right)^{4}=- \frac{9^{4}}{2^{4}}=\ldots \text{ZRM}\)
12. \(-\left(\frac{-19}{4}\right)^{-4}=-\left(-\frac{4}{19}\right)^{4}=- \frac{4^{4}}{19^{4}}=\ldots \text{ZRM}\)
