Evaluate limit of the form $0^{\infty}$ $$\lim_{n\to\infty}\left(\frac{n^4-3\cdot n^3-n^2+2\cdot n-1}{n^5+n^4-n^3-3\cdot n^2-3\cdot n+1}\right)^{\frac{6\cdot n^5-2\cdot n^4-2\cdot n^3+n^2-2\cdot n}{9\cdot n^4-2\cdot n^3+n^2+3\cdot n}}$$
It is $$\lim_{n\to \infty}\left(\frac{1}{n}+o\left(\frac{1}{n^2}\right)\right)^{(n+o(1))}$$
How can I bring it to a form that I can compute?

There is no hesitation with $0^\infty$, which can be read as $\dfrac1{\infty^\infty}$.
