Applicare la formula: $\log_{b}\left(mn\right)$$=\log_{b}\left(m\right)+\log_{b}\left(n\right)$, dove $mn=8\sqrt{x}$, $b=4x$, $b,mn=4x,8\sqrt{x}$, $m=\sqrt{x}$ e $n=8$

Applicare la formula: $\log_{b}\left(x\right)$$=\log_{b}\left(pfgmin\left(x\right)\right)$, dove $b=4x$ e $x=8$

Applicare la formula: $\log_{b}\left(x^a\right)$$=a\log_{b}\left(x\right)$, dove $a=\frac{1}{2}$ e $b=4x$

Applicare la formula: $\log_{b}\left(x^a\right)$$=a\log_{b}\left(x\right)$, dove $a=3$, $b=4x$ e $x=2$
