Final answer:
The population of Austria is 0.614 x 10^6 more than the population of Switzerland.
Step-by-step explanation:
To find the difference in population between Austria and Switzerland, we need to subtract the population of Switzerland from the population of Austria.
Population of Austria = 8.397 x 106
Population of Switzerland = 7.783 x 106
Difference in population = Population of Austria - Population of Switzerland
Difference in population = (8.397 x 106) - (7.783 x 106)
Difference in population = 0.614 x 106
Therefore, the population of Austria is 0.614 x 106 more than the population of Switzerland.
