The expression is given as ;
[tex](\frac{3}{x^3})^{-2}[/tex]From the expression , you notice that the rules to use in re-writing the expression are:
i) a negative power
ii) A power to a power
So this can be written as
[tex]\lbrack\frac{(3)}{(x^{-3})}\rbrack^{-2}[/tex]Appy power to power rule by product of the exponents to get;
[tex]\frac{(3)^{-2}}{(x^{-3})^{-2}^{}}[/tex][tex]\frac{3^{-2}}{x^6}[/tex]Answer
D. Negative power and power to a power
