integral of 1 to e^4 dx/x(1+lnx)

1+lnx = a => dx/x = da

dx/ x(1+lnx) = da/a

int of da/a = In(a)

=>int of dx/ x(1+lnx) = In(1+In(x)) + C

from 1 to e^4 for int of dx/ x(1+lnx) = In(1+In(1)) - In(1+In(e^4))

In(1+In(1)) - In(1+In(e^4)) = -In(5) =~ -1.60944

I am getting this as the wrong answer am i doing something wrong?
