Estimate the value of 6×2–√.

The given expression is 6×2–√.

First, we need to simplify the expression inside the square root.
Since we don't have any value defined under the square root, we can consider it as 0.

So, the expression becomes 6×2 - 0.
6×2 is equal to 12.

Therefore, the value of 6×2–√ is 12.

To estimate the value of 6×2–√, we need to know the value of the square root. However, the expression as you have written it is incomplete. The square root of what? Please provide the complete expression, and I will be happy to help you estimate the value step-by-step.
