To determine the best estimate of the number 866,214,000,000, we can express this number in scientific notation.
The number 866,214,000,000 can be written as:
\[ 8.66214 \times 10^{11} \]
Now let's compare this with the given options:
1. \( 9 \times 10^{11} \)
2. \( 8 \times 10^{11} \)
3. \( 10 \times 11^{10} \) (This appears to be incorrectly formatted for scientific notation)
4. \( 8–11 \times 10 \) (also seems incorrectly formatted)
Among the valid options, we have \( 9 \times 10^{11} \) and \( 8 \times 10^{11} \).
The actual value \( 8.66214 \times 10^{11} \) is closer to \( 9 \times 10^{11} \) than to \( 8 \times 10^{11} \).
Thus, the best estimate of the number 866,214,000,000 is:
**\( 9 \times 10^{11} \)**.
