Applicare la formula: $\ln\left(a\right)-\ln\left(b\right)$$=\ln\left(\frac{a}{b}\right)$, dove $a=x+8$ e $b=3$

Applicare la formula: $\ln\left(a\right)-\ln\left(b\right)$$=\ln\left(\frac{a}{b}\right)$, dove $a=\frac{x+8}{3}$ e $b=x$

Applicare la formula: $\frac{\frac{a}{b}}{c}$$=\frac{a}{bc}$, dove $a=x+8$, $b=3$, $c=x$, $a/b/c=\frac{\frac{x+8}{3}}{x}$ e $a/b=\frac{x+8}{3}$
