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: \(1,400,000,000\) which is equal to \(1.4 \times 10^9\)
Now we can do the subtraction:
\[ 1.45 \times 10^9 - 1.4 \times 10^9 \]
\[ = (1.45 - 1.4) \times 10^9 \]
\[ = 0.05 \times 10^9 \]
To express \(0.05\) in scientific notation, we can write:
\[ 0.05 = 5 \times 10^{-2} \]
So:
\[ 0.05 \times 10^9 = 5 \times 10^{-2} \times 10^9 = 5 \times 10^{7} \]
Thus, the number of more people living in China than in India is:
\[ 5 \times 10^{7} \]
So the answer is:
5×10^7 (5 times 10 superscript 7 baseline)
