Let \(L\) and \(K\) be two fields with \(L\) a simple extension of \(K\). By \(R(L/K)\) the author means the rank of the tensor associated to multiplication in \(L\) viewed as an \(K\)-algebra. In this paper the author shows that \(R(\mathbb{F}_{q^ n}/\mathbb{F}_ q)\) has one of two possible values when \({1\over 2}q+1
