Evaluate: \(\sqrt{257} \times 19.17 + 8.15 \times 13.78\).

1. 406
2. 450
3. 432
4. 416

Correct answer: 416

Solution

Approximating \(\sqrt{257} \approx 16\), we get \(16 \times 19.17 = 306.72\). Also, \(8.15 \times 13.78 \approx 112.27\). Their sum is about \(418.99\), and the closest option given is 416, which is the intended answer from the approximation-based question.
