Applicare la formula: $a^x=b$$\to \log_{a}\left(a^x\right)=\log_{a}\left(b\right)$, dove $a=5$, $b=1$ e $x=x+6$

Applicare la formula: $\log_{a}\left(b\right)$$=logf\left(b,a\right)$, dove $a=5$, $b=1$ e $a,b=5,1$

Applicare la formula: $\log_{b}\left(b^a\right)$$=a$, dove $a=x+6$ e $b=5$

Applicare la formula: $x+a=b$$\to x+a-a=b-a$, dove $a=6$, $b=0$, $x+a=b=x+6=0$ e $x+a=x+6$

Applicare la formula: $x+a+c=b+f$$\to x=b-a$, dove $a=6$, $b=0$, $c=-6$ e $f=-6$
