Feb 3, 2021 · So that's the "proof". The failure is at step 5, where you say that pq = pr p q = p r implies that q = r q = r; that's true only if you know p p is nonzero. For instance 0 ⋅ 5 = 0 ⋅ 7 0 ⋅ …

You got the general expansion about x = a. Here we are intended to take a = 0. That is, we are finding the Maclaurin series of ln(1 + x). That will simplify your expression considerably. Note …
