Answer:

A

Step-by-step explanation:

-\left(3^{-5}\right)\left(3^3\right)

\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^{b+c}

3^{-5}\cdot \:3^3=3^{-5+3}

= -3^{-5}\cdot \:3^3

\mathrm{Add/Subtract\:the\:numbers:}\:-5+3=-2

=-3^{-2}

= \mathrm{Apply\:exponent\:rule}:\quad \:a^{-b}=\frac{1}{a^b}

3^{-2}=\frac{1}{3^2}

= =-\frac{1}{3^2}

3^2=9

= =-\frac{1}{9}
