Answer 2

Answer :

$\large \sf \implies 50$

Solution :

To evaluate : $\sf (2^{-1} \times 5^{-1})^{-1}\div 5^{-1}$

Let's solve,

$\sf (2^{-1} \times 5^{-1})^{-1}\div 5^{-1}\\ \\ \implies \sf (\frac{1}{2 }\times \frac{1}{5})^{-1}\div \frac{1}{5} \\ \\ \sf \implies (\frac{1}{10}) ^{-1} \div \frac{1}{5} \\ \\ \implies \sf 10 \div \frac{1}{5} \\ \\ \implies 10 \times 5 \\ \\ \implies 50$

Hence,

$\sf (2^{-1} \times 5^{-1})^{-1}\div 5^{-1} = \large 50$
