$$\begin{gathered} \lim \frac{2n^4-3n^3+2}{n^3+2}=\lim \frac{n^4\left(2-\frac{3}{n}+\frac{2}{n^4}\right)}{n^3\left(1+\frac{2}{n^3}\right)} \\ =\lim \left[n.\frac{2-\frac{3}{n}+\frac{2}{n^4}}{1+\frac{2}{n^3}}\right]=+\infty \end{gathered}$$

Vì $\lim n=+\infty ; \lim \frac{2-\frac{3}{n}+\frac{2}{n^4}}{1+\frac{2}{n^3}}=2$
