what is the integral of ln 7x? natual log of 7x?

Question

please 4give me, but ur help is really appreciated cos the system is rejecting my answer.
the actual question is the integral of 2/( x ln 7x) with respect to d.. meaning after 2/(xLn7x) dx... hope u got this?
i have to submit it on saturday, b4 6pm.. thanks

Answer 1

Depends between what x values. from a to b

solution:
split up the integral
integral of 2 - integral of (x ln 7x)
integral of 2 -(integral of x + integral of ln (7x))
Use fundamental theorem of calculus
(2x-.5(x^2)-(integral of ln 7x)) multiplied by (b-a)

Sorry, I'm too lazy to figure out integral of ln 7x

Good luck.
