$\dfrac{-4\cdot (-3)^{-17}-(-3)^{-16}}{9^{-9}\cdot 45}=\dfrac{(-3)^{-16}\cdot \Big(\frac{-4\cdot (-3)^{-17}}{(-3)^{-16}}-\frac{(-3)^{-16}}{(-3)^{-16}}\Big)}{(3^2)^{-9}\cdot 9\cdot 5}=\\\\\\=\dfrac{(-3)^{-16}\cdot (-4\cdot (-3)^{-1}-1)}{(3^2)^{-9}\cdot 9\cdot 5}=\dfrac{(-3)^{-16}\cdot (-4\cdot \frac{1}{-3}-1)}{3^{-18}\cdot 3^2\cdot 5}=\\\\\\=\dfrac{3^{-16}\cdot (\frac{4}{3}-1)}{3^{-16}\cdot 5}=\dfrac{\frac{1}{3}}{5}=\dfrac{1}{3\cdot 5}=\dfrac{1}{15}$
