• \[\left( \frac{2}{3} \times \frac{5}{7} \right)^{- 5}\]

   

• \[\left( \frac{2}{3} \times \frac{5}{7} \right)^{25}\]

   

• \[\left( \frac{2}{3} \times \frac{5}{7} \right)^{- 25}\]

   

Answer 1

\[\left( \frac{2}{3} \times \frac{5}{7} \right)^{- 5}\]
We have: 
\[\left( \frac{2}{3} \right)^{- 5} \times \left( \frac{5}{7} \right)^{- 5}\] `=(2/3xx5/7)^(-5)`    → ((a x b)ⁿ = aⁿ x bⁿ)
