To determine how many more people live in China than in India, we need to compare the two populations.
China's population is approximately \(1.45 \times 10^9\).
India's population is \(1,400,000,000\), which can be rewritten in scientific notation as \(1.4 \times 10^9\).
Next, we find the difference between China's population and India's population:
\[ 1.45 \times 10^9 - 1.4 \times 10^9 = (1.45 - 1.4) \times 10^9 = 0.05 \times 10^9 \]
Now, we can express \(0.05 \times 10^9\) in standard scientific notation:
\[ 0.05 \times 10^9 = 5 \times 10^{-2} \times 10^9 = 5 \times 10^{7} \]
Therefore, the difference in population is \(5 \times 10^{7}\).
Thus, the correct response is:
5×10^7 (5 times 10 superscript 7 baseline).
