\( (\frac{2}{5})^3 \times (\frac{2}{5})^{-9} \)
\( (-\frac{5}{4})^{-6} \times (\frac{7}{5})^{-6} \)
\( 8^{-2} \times (\frac{1}{5})^6 \)
\( \frac{(-\frac{5}{7})^{10}}{(\frac{5}{7})^6} \)
\( \frac{(-\frac{11}{3})^9}{(-\frac{5}{2})^9} \)
\( \sqrt{\frac{9}{25}} \times (\frac{3}{5})^{-14} \times \frac{27}{125} \)
