A student is attempting to calculate the square root of 9. His work is shown below. Which statement below best applies
to his mathematical reasoning?
N
Given . I observe that 9 is not a perfect square. I notice the perfect squares closest to 9 are 4 and 16, so I estimate the
answer to be somewhere between 4 and 116. Since 9 is closer to 4 than 16, I estimate V6 2.5.
A. 9 is a perfect square, and the radical could have been evaluated directly.
B. 4 and 16 are not perfect squares, and therefore the student should not have chosen those numbers to
estimate 9.
C. The student should not have evaluated 4 to estimate 9.
D. The student has made no error. 10 s 25.
