WebSince k ≥ 5, then 4 < 32 ≤ 2k. Then, applying this inequality to the RHS of Equaiton (II) and simplifying, we get 2 k + 4 < 2 k + 2 k = 2×2 k = 2 1 ×2 k = 2 k+1 (III) We established, in Equation (I), that the LHS of Equation (I) is less than the RHS of Equation (II) — which is also the LHS of Equation (III).
