Question

How do u do this omggg

Answer 1

`\bf \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}`

`\bf \cfrac{a^n}{a^m}\implies a^na^(-m)\implies a^(n-m) \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \boxed{1}~\hspace{5em}\cfrac{2^4}{2^1}\implies 2^4\cdot 2^(-1)\implies 2^(4-1)\implies 2^3\implies 8 \\\\\\ \boxed{2}~\hspace{5em}\cfrac{x^3}{x^2}\implies x^3\cdot x^(-2)\implies x^(3-2)\implies x^1\implies x \\\\\\ \boxed{6}~\hspace{5em}\cfrac{(-3)^6}{(-3)^2}\implies (-3)^6\cdot (-3)^(-2)\implies (-3)^(6-2)\implies (-3)^4 \\\\\\ ~\hspace{6em}(-3)(-3)(-3)(-3)\implies 81`
