To find out how many more people live in China than in India, we need to convert India's population into scientific notation as well.
India's population is approximately 1,400,000,000. In scientific notation, this can be expressed as: \[ 1.4 \times 10^9 \]
Now let's compare the two populations in scientific notation:
- China's population: \( 1.45 \times 10^9 \)
- India's population: \( 1.4 \times 10^9 \)
Now, we will subtract India's population from China's population: \[ 1.45 \times 10^9 - 1.4 \times 10^9 \]
To perform the subtraction, we can factor out \( 10^9 \): \[ (1.45 - 1.4) \times 10^9 = 0.05 \times 10^9 \]
Now we convert \( 0.05 \) into scientific notation: \[ 0.05 = 5 \times 10^{-2} \]
So, we have: \[ 0.05 \times 10^9 = 5 \times 10^{-2} \times 10^9 = 5 \times 10^7 \]
Thus, the final answer is: 5 × 10^7 (5 times 10 superscript 7 baseline).
