Final Answer:
In 2010, the population of Austria was about 614,000 more than the population of Switzerland.
Step-by-step explanation:
Given that the population of Austria in 2010 was 8.397 × 10⁶ and the population of Switzerland in 2010 was 7.783 × 10⁶, we can calculate the difference between the two populations:
8.397 × 10⁶ - 7.783 × 10⁶ = 614,000
Therefore, the population of Austria was about 614,000 more than the population of Switzerland in 2010.
