(5/8)^-7=(8/5)⁷

(8/5)^-5=(5/8)⁵

then

8⁷x5⁵/5⁷x8⁵

8²/5²

64/25

2.63

Answer 2

Answer:

$\frac {8^2}{5^2}$ => $\frac {64}{25}$

Step-by-step explanation:

=> $\frac {5^{-7}}{8^{-7}}$ * $\frac {8^{-5}}{5^{-5}}$

=> $\frac {5^{-7}}{5^{-5}}$ * $\frac {8^{-5}}{8^{-7}}$

=> $\frac {5^{-2}}{1}$ * $\frac {1}{8^{-2}}$

=> $\frac {1}{5^{2}}$ * $\frac {8^{2}}{1}$

=> $\frac {8^2}{5^2}$

=> $\frac {64}{25}$
