To find out how many more people live in China than in India, we need to subtract India's population from China's population.
China's population: 1.45 × 10^9
India's population: 1,400,000,000
To convert India's population to scientific notation, we can write it as 1.4 × 10^9.
Now let's subtract:
1.45 × 10^9 - 1.4 × 10^9 = 0.05 × 10^9
Since 0.05 × 10^9 is the same as 5 × 10^8, the answer is:
5 × 10^8
So, there are 5 × 10^8 (500,000,000) more people living in China than in India.
To find out how many more people live in China than in India, we need to subtract the population of India from the population of China.
China's population is approximately 1.45x10^9 (1.45 billion), while India's population is approximately 1.4x10^9 (1.4 billion).
So, we subtract the population of India from the population of China:
1.45x10^9 - 1.4x10^9 = 0.05x10^9
Simplifying, 0.05x10^9 is equal to 5x10^8.
Therefore, there are 5x10^8 (500 million) more people living in China than in India.
So the correct answer is 5x10^8.
