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

Applicare la formula: $\frac{\frac{a}{b}}{c}$$=\frac{a}{bc}$, dove $a=\ln\left(n\right)$, $b=\ln\left(c\right)$, $c=n^b$, $a/b/c=\frac{\frac{\ln\left(n\right)}{\ln\left(c\right)}}{n^b}$ e $a/b=\frac{\ln\left(n\right)}{\ln\left(c\right)}$

Applicare la formula: $\lim_{x\to c}\left(a\right)$$=a$, dove $a=\frac{\ln\left(n\right)}{n^b\ln\left(c\right)}$ e $c=0$
