Answer:

-10

Step-by-step explanation:

Hii Mate ✌

(2⁻¹÷5⁻¹)² × (-5/8)⁻¹

= (1/2 ÷ 1/5)² × (-8/5)

= (5/2)² × (-8/5)

= - (25/4) × (8/5)

= -10

100% CORRECT ✔️✔️

HOPE IT HELPS YOU,

PLEASE THANK AND MARK AS BRAINLIEST.

ANSWER✔

\large\underline\bold{GIVEN,}

\sf\dashrightarrow \: (2^{-1} \div 5^{-1} )\times \bigg( \dfrac{-5}{8} \bigg)^{-1}

✯IDENTITY IN USE,

\large{\boxed{\bf{ \star\:\: (a)^{-1}= \bigg( \dfrac{1}{a}\bigg)^1  \:\: \star}}}

\large\underline\bold{SOLUTION,}

\sf\dashrightarrow (2^{-1} \div  5^{-1} )\times \bigg( \dfrac{-5}{8} \bigg)^{-1}

\sf\implies \left( \bigg( \dfrac{1 }{2} \bigg)^1 \div \bigg( \dfrac{1}{5} \bigg)^1 \right)^2 \times \bigg( \dfrac{-5}{8} \bigg)^{-1}

\sf\implies \left( \dfrac{1}{2} \times 5 \right)^2 \times \bigg( \dfrac{-8}{5} \bigg)

\sf\implies \bigg( \dfrac{5}{2} \bigg) ^2 \times \bigg( \dfrac{-8}{5 } \bigg)

\sf\implies \dfrac{25}{4} \times \dfrac{-8}{5}

\sf\implies \dfrac{-200}{20}

\sf\implies \cancel \dfrac{-200}{20}

\sf\implies -10

\large{\boxed{\bf{ \star\:\: (2^{-1} \div 5^{-1} )\times \bigg( \dfrac{-5}{8} \bigg)^{-1}= -10 \:\: \star}}}
