To find out how many more people live in China than in India, we need to compare the two populations.
China’s population: \( 1.45 \times 10^9 \)
India’s population: \( 1,400,000,000 = 1.4 \times 10^9 \)
Now we subtract India's population from China's population:
\[
1.45 \times 10^9 - 1.4 \times 10^9 = (1.45 - 1.4) \times 10^9 = 0.05 \times 10^9
\]
Now we can express \( 0.05 \times 10^9 \) in standard form:
\[
0.05 \times 10^9 = 5 \times 10^8
\]
So, the answer is:
**\( 5 \times 10^8 \)**
This means there are 50 million more people living in China than in India.

\[
1.45 \times 10^9 - 1.4 \times 10^9 = (1.45 - 1.4) \times 10^9 = 0.05 \times 10^9
