[MARK THE ANSWER AS BRAINLIEST]

Step-by-step explanation:

$( \frac{5}{8})^{-7} *(\frac{8}{5} )^{-5}$

$[ Using \ (\frac{x}{y} )^{m} \ = \ ( \frac{y}{x} )^{-m} ]$

⇒ $(\frac{8}{5} )^{7}*(\frac{8}{5} )^{-5}$

$[ Using \ a^{m} *a^{n} =a^{m+n} ]$

⇒ $(\frac{8}{5} )^{7-5}$

⇒ $(\frac{8}{5} )^{2}$

⇒ $\frac{64}{25}$
