answer with full explanation​

Answer 1

Answer:

2/25

Step-by-step explanation:

${( {4}^{ - 1} - {5}^{ - 1} )}^{2} \times {( \frac{5}{8} )}^{ - 1} \\ (\frac{1}{ {4}^{1} } - \frac{1}{ {5}^{1} } ) \times \frac{ {5}^{ - 1} }{ {8}^{ - 1} } \\ ( \frac{1}{4} - \frac{1}{5} ) \times \frac{ \frac{1}{5} }{ \frac{1}{8} } \\ ( \frac{5}{20} - \frac{4}{20} ) \times \frac{8}{5} \\ \frac{1}{20} \times \frac{8}{5} \\ \frac{1}{5} \times \frac{2}{5} \\ \frac{2}{25}$
