To find out how many more people live in China than in India, we can subtract India's population from China's population.
China's population: \( 1.45 \times 10^9 \)
India's population: \( 1,400,000,000 = 1.4 \times 10^9 \)
Now we can perform the subtraction:
\[ 1.45 \times 10^9 - 1.4 \times 10^9 = (1.45 - 1.4) \times 10^9 = 0.05 \times 10^9 = 5 \times 10^7 \]
So, China has \( 5 \times 10^7 \) more people than India.
Therefore, the correct answer is:
5×10^7
