Answer 1

Answer:

A. 81

Step-by-step explanation:

The given expression is:

`3^{(11)/(5)}/3^{-(9)/(5)}`

Note that:

`a^b/ a^c=a^(b-c)`

Applying the rule of indices above to the given expression

`\begin{gathered} 3^{(11)/(5)}/3^{-(9)/(5)} \\ \\ 3^{(11)/(5)-(-(9)/(5))} \\ \\ 3^{(11)/(5)+(9)/(5)} \\ \\ 3^{(20)/(5)} \\ \\ =3^4 \\ \\ =81 \end{gathered}`
