\left(\dfrac{3a^{-3}b^2}{2a^{-1}b^0}\right)^2

First some simplifying:

\left(\dfrac{3a^1b^2}{2a^3b^0}\right)^2=\left(\dfrac{3b^2}{2a^2}\right)^2=\dfrac{9b^4}{4a^4}

Then with a=-2 and b=-3, we have a^4=(-2)^4=16=4^2 and b^4=(-3)^4=81=9^2, so

\dfrac{9b^4}{4a^4}=\dfrac{9\cdot9^2}{4\cdot4^2}=\dfrac{9^3}{4^3}=\dfrac{729}{64}
