Applicare la formula: $\log_{b}\left(\frac{x}{y}\right)$$=\log_{b}\left(x\right)-\log_{b}\left(y\right)$, dove $b=\frac{1}{3}$, $x=\sqrt{x}$ e $y=yz$

Applicare la formula: $\log_{b}\left(mn\right)$$=\log_{b}\left(m\right)+\log_{b}\left(n\right)$, dove $mn=yz$, $b=\frac{1}{3}$, $b,mn=\frac{1}{3},yz$, $m=y$ e $n=z$

Applicare la formula: $\log_{b}\left(x^a\right)$$=a\log_{b}\left(x\right)$, dove $a=\frac{1}{2}$ e $b=\frac{1}{3}$

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