The answer that uses the most appropriate units is:
4.39814¯¯¯¯¯¯¯¯¯¯¯¯ × 10^2 days.
To determine the answer that uses the most appropriate units, we need to compare the magnitudes of the given options.
Let's analyze each option:
1.05¯¯¯¯¯ × 10^4 hours: This option represents 10^4 or 10,000 hours.
4.39814¯¯¯¯¯¯¯¯ × 10^2 days: This option represents 10^2 or 100 days.
6.3¯¯¯ × 10^5 minutes: This option represents 10^5 or 100,000 minutes.
3.8×10^7 seconds: This option represents 10^7 or 10,000,000 seconds.
Comparing the magnitudes, we can see that the option with the highest magnitude is 3.8×10^7 seconds. Therefore, the answer that uses the most appropriate units is 3.8×10^7 seconds.
