$$\int \frac{d x}{x \log{\left(x \right)}}\, dx = C + d \operatorname{li}{\left(x \right)}$$
Simplify
The answer [src] 
d*li(100) - d*li(10)
$$- d \operatorname{li}{\left(10 \right)} + d \operatorname{li}{\left(100 \right)}$$ 
=
= 
d*li(100) - d*li(10)
$$- d \operatorname{li}{\left(10 \right)} + d \operatorname{li}{\left(100 \right)}$$ 
d*li(100) - d*li(10)
