Proof of linear independence induction

WebProof. The proof is by induction on n. Suppose that ρ is a positive integer that is not a perfect square. Then {1, √ ρ} certainly spans Q(√ ρ), since every element of the latter is of the form a+b √ ρ for a,b ∈ Q. Linear independence follows from Theorem 3. Hence the Lemma holds for n = 1. The Lemma also holds for n = 0, since {1 ... WebMar 5, 2024 · The theorem is an if and only if statement, so there are two things to show. ( i.)
