b)a^2/3b
c)3a^2/b
d)Already simplified

Answer 1

the answer is 3a^2b

Explanation:

Answer 2

`\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)} \\\\ -------------------------------\\\\ \cfrac{3b}{a^(-2)}\implies 3a^2b`
