What is the value of (11^2+8^2)?

Advertisement

Answer and explanation

Correct answer: 185

Evaluate the two powers first: 11² = 121 and 8² = 64. Therefore, 11² + 8² = 121 + 64 = 185, so option B is correct. In an exam, calculating each square separately before adding helps avoid arithmetic errors.
