The solution
You have entered
[src]
100 / | | d*x | -------- dx | x*log(x) | / 10
$$\int\limits_{10}^{100} \frac{d x}{x \log{\left(x \right)}}\, dx$$
Integral((d*x)/((x*log(x))), (x, 10, 100))
The answer (Indefinite)
[src]
/ | | d*x | -------- dx = C + d*li(x) | x*log(x) | /
$$\int \frac{d x}{x \log{\left(x \right)}}\, dx = C + d \operatorname{li}{\left(x \right)}$$
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)
