The first integral (1/x5) is a straightforward power rule problem—just plug in the formula and go home happy. The second one? That "+1" transforms it into a special functions nightmare that would make even seasoned mathematicians curl up in the fetal position.
It's the calculus equivalent of going from "let's grab a quick coffee" to "surprise, we're climbing Everest without oxygen." That tiny "+1" is why math professors drink heavily after grading exams and why students develop eye twitches during finals week.
