Applicare la formula: $\lim_{x\to c}\left(a^b\right)$$=\lim_{x\to c}\left(e^{b\ln\left(a\right)}\right)$, dove $a=x$, $b=\frac{2}{\ln\left(x\right)}$ e $c=\infty $

Applicare la formula: $a\frac{b}{c}$$=\frac{ba}{c}$, dove $a=\ln\left(x\right)$, $b=2$ e $c=\ln\left(x\right)$

Applicare la formula: $\frac{a}{a}$$=1$, dove $a=\ln\left(x\right)$ e $a/a=\frac{2\ln\left(x\right)}{\ln\left(x\right)}$

Applicare la formula: $\lim_{x\to c}\left(a\right)$$=a$, dove $a=e^2$ e $c=\infty $
