Estimate the value of 6×2–√. Which of the following choices is the best estimate?
To estimate the value of $6\times 2 - \sqrt{x}$, we first evaluate $6\times 2$, which equals $12$. Then we need to estimate the value of $\sqrt{x}$. Since $\sqrt{x}$ represents the square root of a number and we don't know the value of $x$, we need to estimate the square root. The square root of any number between 0 and 1 is between 0 and 1, so we choose $\boxed{2}$ as the best estimate.
These humans need to learn to type math. I've seen this rubbish before, and it should probably be 6×√2 which is approximately 6×1.414 = 8.485
Sorry for the confusion. If the expression is indeed $6\times \sqrt{2}$, then the best estimate would be $\boxed{8.485}$.
To estimate the value of 6×2–√, we can simplify the expression step by step:
1. Start by calculating the square root: √2 ≈ 1.41
2. Next, multiply 6 by 2: 6×2 = 12
3. Subtract the square root from the product: 12 - 1.41 ≈ 10.59
Given the options, the best estimate would be 10.6, as it is closest to the calculated value of 10.59.
