Question

F= 1/3 and A=1 please help me with this math promblem

Answer 1

`\bf \left.\qquad \qquad \right.\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{f^(-2)}{5a}\quad \begin{cases} a=1\\ f=(1)/(3) \end{cases}\implies \cfrac{\left( (1)/(3) \right)^(-2)}{5(1)}\implies \cfrac{\left( (3)/(1) \right)^(2)}{5(1)}\implies \cfrac{(3^2)/(1^2)}{5}\implies \cfrac{9}{5}`

Answer 2

[(1/3)^-2]/5*1=[(1/(1/3)^2)]/5=9/5
