Question

China has a population of approximately 1,382,323,332 people. The population of the United States is about 324,118,787 people. Using scientific notation, give the approximation for each population.

Answer 1

The populations of China and the United States can be approximated using scientific notation.

Step-by-step explanation:

To approximate the populations of China and the United States using scientific notation, follow these steps:

1. Write the population of China, 1,382,323,332, with a decimal point after the first digit: 1.382323332
2. Multiply this number by 10 raised to the power of 9, since there are 9 digits after the decimal point: 1.382323332 x 10⁹
3. Write the population of the United States, 324,118,787, with a decimal point after the first digit: 3.24118787
4. Multiply this number by 10 raised to the power of 8, since there are 8 digits after the decimal point: 3.24118787 x 10⁸

Therefore, the approximation for the population of China in scientific notation is 1.382323332 x 10⁹, and the approximation for the population of the United States is 3.24118787 x 10⁸.

Answer 2

China's population = 1.382 * 10^9
United State's population = 3.241 * 10^8

You can add more numbers to the decimal if your teacher prefers it that way, although generally you don't go past three decimal places
