To express the population of China, which is approximately 1,322,000,000, in scientific notation, we identify the first digit (1) and place the decimal point after it, giving us 1.322. We then count how many places we moved the decimal point to get from 1,322,000,000 to 1.322.

In this case, we moved the decimal point 9 places to the left. Thus, we multiply by \(10^9\).

So, the correct scientific notation for China's population is:

1.322 × 10^9.

Therefore, the correct response is: 1.322 × 10^9 (1 point 3 2 2 times 10 to the 9th power).
