Abstract
Let be any field. Let be a degree hypersurface. Under some conditions, we prove that if for some extension with and , then for some extension with , , and . Moreover, if a -solution is known explicitly, then we can compute explicitly as well. As an application, we improve upon a result by Coray on smooth cubic surfaces by showing that if for some extension with , then for some with .
