Applicare la formula: $\ln\left(\frac{a}{b}\right)$$=\ln\left(a\right)-\ln\left(b\right)$, dove $a=x^2$ e $b=yz^3$

Applicare la formula: $\ln\left(x^a\right)$$=a\ln\left(x\right)$, dove $a=2$

Applicare la formula: $\ln\left(ab\right)$$=\ln\left(a\right)+\ln\left(b\right)$, dove $a=y$ e $b=z^3$

Applicare la formula: $\ln\left(x^a\right)$$=a\ln\left(x\right)$, dove $a=3$ e $x=z$

Applicare la formula: $-\left(a+b\right)$$=-a-b$, dove $a=\ln\left(y\right)$, $b=3\ln\left(z\right)$, $-1.0=-1$ e $a+b=\ln\left(y\right)+3\ln\left(z\right)$
