How to expand $r^{d-2}/(r^d-m)$ about $r = m^{1/d}$? Obviously it should be a Laurent series, whose coeffs I can in principle find doing the contour integrals as in the "definition" of Laurent series. But sometimes, taking some factor out, one can use standard binomial expansions to write down the Laurent series. I was wondering whether that sort of thing can be done here
