Abstract
Let k be a field, and let ? and ? be two algebraic numbers over k of degree d and l, respectively. We find necessary and sufficient conditions under which deg(??)=dl and deg(? + ?)=dl. Since these conditions are quite difficult to check, we also state a simple sufficient condition for such equalities to occur.
