To find how many more people live in China than in India, we need to compare their populations.
China's population is approximately \(1.45 \times 10^9\).
India's population is \(1,400,000,000\), which can also be expressed in scientific notation as \(1.4 \times 10^9\).
Now, we can perform the subtraction:
\[ 1.45 \times 10^9 - 1.4 \times 10^9 = (1.45 - 1.4) \times 10^9 = 0.05 \times 10^9 \]
This can be expressed in standard form as:
\[ 0.05 \times 10^9 = 5 \times 10^7 \]
Thus, China has approximately \(5 \times 10^7\) more people than India.
The correct answer is \(5 \times 10^7\).
