Find an expression for $\displaystyle \int_1^s \frac {1}{x^m} dx$ in terms of m and s, where m is a positive rational number, m != -1 and s > 1. Show that the infinte integral $\displaystyle \int_1^\infty \frac {1} {x^m} dx$ has a meaning if m > 1, and state its value in terms of m.

Is it asking me to integrate and come up with a simplified expression? I did that, but it's not matching the answer on multiple attempts.
