Estimated the value of 6 x ✓2. Which of the following choices is the best estimate?
A. 9.8
B. 6.4
C. 8.4
D. 7.1
The value of 6 x √2 is approximately 8.49. Therefore, the best estimate from the given choices is C. 8.4.
To estimate the value of 6 x √2, we can first estimate the value of √2, which is approximately 1.4 (because √2 is between 1 and 2).
Next, we multiply 6 by 1.4: 6 x 1.4 = 8.4.
Therefore, the best estimate for 6 x √2 is 8.4.
The correct choice is C. 8.4.
