What is the value of (13^2+14^3)?

Answer and explanation

Correct answer: 2913

Evaluate the powers first: 13^2 = 13 × 13 = 169 and 14^3 = 14 × 14 × 14 = 2744. Therefore, 169 + 2744 = 2913, so option B is correct. In an exam, calculate each power separately before performing the addition to avoid arithmetic errors.
