    The "-" means you should invert. --- The "3" means you should take the cube root --- The "2" means you shour square. ---- These operations can be done in any order. --- Taking the cube root first you get: 3^-2 --- Inverting you get: (1/3)^2 --- Squaring you get: 1/9

    remember, \[x^{-\#} \rightarrow \frac{1}{x^{\#}}\]
