Question

I just need the answer not how to do it

Answer 1

`\begin{gathered} \frac{3^{(11)/(5)}}{3^{(-9)/(5)}} \\ \text{But from the law of indices} \\ (a^b)/(a^c)=a^(b-c) \\ \frac{3^{(11)/(5)}}{3^{(-9)/(5)}}=3^{(11)/(5)-(-(9)/(5)_{})}=3^{(20)/(5)} \\ \frac{3^{(11)/(5)}}{3^{(-9)/(5)}}=3^4 \\ \frac{3^{(11)/(5)}}{3^{(-9)/(5)}}=3*3*3*3 \\ \frac{3^{(11)/(5)}}{3^{(-9)/(5)}}=81 \end{gathered}`

The correct option is B: 81
