Answer 1

`~\hspace{7em}\textit{negative exponents} \\\\ a^(-n) \implies \cfrac{1}{a^n} ~\hspace{4.5em} a^n\implies \cfrac{1}{a^(-n)} ~\hspace{4.5em} \cfrac{a^n}{a^m}\implies a^na^(-m)\implies a^(n-m) \\\\[-0.35em] ~\dotfill\\\\ (4)^{(-4)/(2)} \implies (4)^(-2)\implies 4^(-2)\implies \cfrac{1}{4^2}\implies \cfrac{1}{16}`
