Question

Evaluate k to the 6th power times p to the -7 power when k is 2 and p is -1

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}\\\\ k^6p^(-7)~~ \begin{cases} k=2\\ p=-1 \end{cases}\implies (2)^6(-1)^(-7)\implies \cfrac{2^6}{(-1)^7}\implies \cfrac{64}{-1}\implies -64`
