√3584 * 52.034 = _______?
Correct answer: C. 3120
- A. 3180
- B. 3200
- C. 3120
- D. 3210
Explanation
Since 3584 = 256 x 14, √3584 = 16√14, which is approximately 59.87. Then 59.87 x 52.034 is approximately 3115, whose nearest listed value is 3120, option c. The likely mistake is choosing a, 3180, from overestimating the square root or product.
