Detailed Solution

The given integral is 1log(xx)(logx+1)dx

Use the logarithmic property logxx=xlogx, the given integral can be written as 

1log(xx)(logx+1)dx=1xlogxlogx+1dx

Suppose that logx=t1xdx=dt

Hence, the given intergal becomes 1t1+tdt

Use partial fractions to find this integral

hence, 

   1t1+tdt=1t-11+tdt =lnt-ln1+t =lnlogx-ln1+logx+C =loglogx1+logx+C

Therefore, 1log(xx)(logx+1)dx=loglogx1+logx+C
