Question

Which is the simplified form of (9c^-9)^-3

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)}\\\\ -------------------------------\\\\ (9c^(-9))^(-3)\impliedby \textit{let's first distribute the exponent} \\\\\\ (9^(-3)c^(-9\cdot -3))\implies 9^(-3)c^(27)\implies \cfrac{1}{9^3}\cdot c^(27)\implies \cfrac{c^(27)}{729}`
