Applicare la formula: $\log_{b}\left(\frac{x}{y}\right)$$=\log_{b}\left(x\right)-\log_{b}\left(y\right)$, dove $b=10$, $x=6y$ e $y=11$

Applicare la formula: $\log_{b}\left(mn\right)$$=\log_{b}\left(m\right)+\log_{b}\left(n\right)$, dove $mn=6y$, $b=10$, $b,mn=10,6y$, $m=y$ e $n=6$

Applicare la formula: $\log_{b}\left(x\right)$$=\log_{b}\left(pfgmin\left(x\right)\right)$, dove $b=10$ e $x=6$

Applicare la formula: $\log_{b}\left(mn\right)$$=\log_{b}\left(m\right)+\log_{b}\left(n\right)$, dove $mn=2\cdot 3$, $b=10$, $b,mn=10,2\cdot 3$, $m=2$ e $n=3$
