Hey there!


\mathsf{x^(-2)}


\mathsf{= -3^(-2)}


\mathsf{= -1 * 3^(-2)}


\mathsf{3^(-2)}


\mathsf{= (1)/(3*3)}


\mathsf{= -1 * (1)/(3*3)}


\mathsf{= -(1)/(3*3)}


\mathsf{3* 3}


\mathsf{= 3^2}


\mathsf{= - (1)/(3^2)}


\mathsf{3^2}


\mathsf{= 3 * 3}


\mathsf{= \bf 9}


\mathsf{-\bf (1)/(9)}


\boxed{\boxed{\huge\text{Answer: }\boxed{\bf - (1)/(9)}}}}\huge\checkmark


\huge\text{Good luck on your assignment \& enjoy your day!}
