Answer 1

`\bf ~~~~~~~~~~~~\textit{negative exponents} \\\\ a^(-n) \implies \cfrac{1}{a^n} \qquad \qquad \cfrac{1}{a^n}\implies a^(-n) \qquad \qquad a^n\implies \cfrac{1}{a^(-n)} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \left( \cfrac{2}{5} \right)^(-2)\implies \left( \cfrac{5}{2} \right)^(+2)\implies \left( \cfrac{5^2}{2^2} \right)\implies \cfrac{25}{4}\implies 6(1)/(4)`
