To estimate the value of \( 6 \times 2 - \sqrt{} \), we first need to clarify the expression correctly, assuming you meant \( 6 \times 2 - \sqrt{something} \) - if we take it as \( 6 \times 2 \) for the estimation:
- Calculate \( 6 \times 2 = 12 \).
- If we assume you want to subtract a square root from 12, let’s simplify it assuming it as \( \sqrt{16} \): \[ 12 - \sqrt{16} = 12 - 4 = 8 \]
Given the choices:
- 7.1
- 9.8
- 8.4
- 6.4
Since we got an estimate close to 8, the best estimate among the options provided would likely be 8.4.
