Estimate the value of 6x√2. Which of the following choices is the best estimate?
A. 7.1
B. 9.8
C. 6.4
D. 8.4
A. 7.1
B. 9.8
C. 6.4
D. 8.4
To estimate the value of 6√2, we need to approximate the value of √2. The square root of 2 is approximately 1.41. Multiplying 6 by 1.41 gives us an estimate of 8.46.
Based on the given choices, the best estimate is D. 8.4.
Based on the given choices, the best estimate is D. 8.4.
