... so F is a splitting field of xq − x. It then follows from our theorem on splitting fields that any two fields of order q are isomorphic. (iii) Let L be a field in which xq − x splits. We observe that the derivative of xq − x is qxq−1 − 1 = −1, since q = pr and we are in characteristic p. Thus, by ou ...
