Applicare la formula: $\int\log_{b}\left(x\right)dx$$=x\log_{b}\left(x\right)-\frac{x}{\ln\left(b\right)}+C$, dove $b=10$ e $x=t$

Applicare la formula: $-\frac{b}{c}$$=\frac{expand\left(-b\right)}{c}$, dove $b=t$ e $c=\ln\left(10\right)$

Applicare la formula: $\left[x\right]_{a}^{b}$$=eval\left(x,b\right)-eval\left(x,a\right)+C$, dove $a=1$, $b=x$ e $x=t\log \left(t\right)+\frac{-t}{\ln\left(10\right)}$
