Answer 2

Answer:
`2.06*10`

Explanation:

Given : The population of china =
`1.3*10^9`

The population of France =
`6.48 * 10^7`

Now, the number of times is greater than the population of China the population of France :-

`n=(1.3*10^9)/(6.48*10^7)\\\\=(1.3)/(6.48)*10^(9-7)\\\\=(1.3)/(6.48)*10^2=(1.3)/(6.48)*100\\\\=20.0617283951\approx20.06=2.06*10`

Hence, the population of China is
`2.06*10` greater than the population of France.
