Let F ⊂ K be fields of characteristic 0, and let K x denote the ring of polynomials with coefficients in K. ∈ F for some j ≥ 1. Suppose that p ∈ K x , q ∈ K x \F x p not constant. Our main result is that p • q / ∈ F x and D F p • q = D F q . With only the assumption that a n b m ∈ F, we prove the i
