Prove by induction n 2 n for all n 4

WebbProve that for all integers n ≥ 4, 3n ≥ n3. PROOF: We’ll denote by P(n) the predicate 3n ≥ n3 and we’ll prove that P(n) holds for all n ≥ 4 by induction in n. 1. Base Case n = 4: Since 34 = 81 ≥ 64 = 43, clearly P(4) holds. 2. Induction Step: Suppose that P(k) holds for some integer k ≥ 4. That is, suppose that for that value of ...
