Evaluate the limit limit gose from x to 4 (x/x4)integral from x to 4

If you mean
∫[x,4] x/(x4) dx
that's a bit unusual to have the variable of integration as one of the limits. But ok, let's work it out asis.
∫x/(x4) dx = x + 4 log(x4)
Evaluating that at 4 and x, we have
(4+4log(0))(x+4log(x4))
Looks like ∞ to me. That upper limit of 4 is a killer
