Mathematics about "integral???"

1) ∫ [ ln(80-q) / 0.1 ] - 30 dq (0 ≤ q ≤ 59.91446)

2) ∫ 7 - [ ln[(x/10)+1] / 0.1] dx (0 ≤ x ≤ 10.13752)

I couldn't know how to solve the question.
Please help me.

You can use substitution to get rid of the inside function inside the ln's, but to integrate the ln's themselves, you can try integration by parts:

Integral of udv = uv - Integral of vdu

u = ln(x)
du = 1/x dx
dv = dx
v = x

So Integral of ln(x)dx = xln(x) - Integral x(1/x)dx = xln(x) - Integral dx = xln(x) - x

10[ 1/80-q -30q] from 0 to 59.91446
