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.
