Applicare la formula: $\log_{b}\left(mn\right)$$=\log_{b}\left(m\right)+\log_{b}\left(n\right)$, dove $mn=\sqrt[4]{x}\sqrt[3]{y}$, $b=10$, $b,mn=10,\sqrt[4]{x}\sqrt[3]{y}$, $m=\sqrt[4]{x}$ e $n=\sqrt[3]{y}$

Applicare la formula: $\log_{b}\left(x^a\right)$$=a\log_{b}\left(x\right)$, dove $a=\frac{1}{4}$ e $b=10$

Applicare la formula: $\log_{b}\left(x^a\right)$$=a\log_{b}\left(x\right)$, dove $a=\frac{1}{3}$, $b=10$ e $x=y$
