irreducible means that the polynomail do not need factorization |k:F| means the degree of k over F i need the answer today if you can :frown:

i forget questions this question Q(2)(a) show the polynomail is irreducible over Q xpower 5+8*(x power 4)+3*(x power 2)+4*x+7 question six(a): Let F subset of K be a field extension show that |K:F|=1 if and only if K=F.
