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

Applicare la formula: $\frac{x}{a}=b$$\to x=ba$, dove $a=\log \left(x\right)$, $b=x$ e $x=\log \left(b+x\right)$

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

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

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