What do you get when you integrate ∫lnX dx?

could you show your solution as well please

Answers:
integrate by parts

int ln(x) dx = x ln(x) - int (1/x)x dx = x ln(x) - int 1 dx

x ln(x) - x
1/x . It's a standard integral.
xln(x)-x
1/x really no work to show.it's on a standard table of integrals
u = ln(x)
du = dx / x

dv = dx
v = x

Then, by the formula:

u*v - integral( v * du )

ln(x)*x - integral(x*dx/x)
ln(x)*x - integral(dx)
ln(x)*x - x + constant
1x or 1. its also usually written in front of derivatives.
Put a little more effort into it. I googled :integrate lnx
and got :
Hence ∫ ln x dx = x ln x - ∫ x (1/x) dx
= x lnx - ∫ dx
= x lnx - x + constant

also the integral of lnX dx is technically

xlnX +C
Yeah, the answer's xlnx - x.

You have to integrate by parts to get it, which someone else already showed the work for.
log x to the n.
To be honest all I get is confused :))
