WebFeb 18, 2024 · It follows from basic algebraic number theory that: There is a factorization ( 2) = P Q as prime ideals in L. There is a factorization ( 2) = p q as prime ideals in K, and the relative norm of P and Q to K is p 11 and q 11 respectively. The norm of p and q are both 2. To show that 2 is irreducible, you need to show that P is not a principal ideal.
