1 answer

To find out how many more people live in China than in India, you can subtract India's population from China's population.

China's population: \(1.45 \times 10^9 = 1,450,000,000\)

India's population: \(1,400,000,000\)

Now, let's do the subtraction:

\[ 1,450,000,000 - 1,400,000,000 = 50,000,000 \]

Now, we can express \(50,000,000\) in scientific notation:

\[ 50,000,000 = 5 \times 10^7 \]

So, the answer is:

5 * 10 ^ 7.
