Applicare la formula: $\log_{b}\left(x\right)$$=\log_{b}\left(pfg\left(x\right)\right)$, dove $b=p$ e $x=75$

Applicare la formula: $\log_{b}\left(mn\right)$$=\log_{b}\left(m\right)+\log_{b}\left(n\right)$, dove $mn=3\cdot 5^{2}$, $b=p$, $b,mn=p,3\cdot 5^{2}$, $m=5^{2}$ e $n=3$

Applicare la formula: $a^b$$=a^b$, dove $a=5$, $b=2$ e $a^b=5^{2}$
