 \:  \star \underline {\boxed{ \sf \color{brown} \: answers}}

 \:  \:  \implies \displaystyle \tt{ ({ \frac{4}{7} })^{ - 2}  \times  { (\frac{ - 4}{7} })^{ - 3}  \div   { (\frac{ - 4}{7} })^{5} }

 \:  \implies \displaystyle \tt{ { \bigg(\frac{ - 4}{7} } \bigg)^{ - 5}   \div  {  \bigg( \frac{ - 4}{7} } \bigg)^{5} }

 \:  \:  \implies \displaystyle \tt{ \frac{ \frac{ { - 4}^{ - 5} }{7} } { \frac{ { - 4}^{5} }{7} } }

  \implies \displaystyle \tt{  {  \bigg(\frac{ - 4}{7} } \bigg)^{ - 10} }
