Question

X^k=1/x^-1
Someone help me please

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\\\\ x^k~~ = ~~\cfrac{1}{x^(-1)}\implies x^k~~ = ~~x^1\implies k=1`
