To express the population of China, which is approximately 1,322,000,000, in scientific notation, we first identify the significant digits and where the decimal point should be placed.
The number 1,322,000,000 can be rewritten as 1.322 when we place the decimal after the first non-zero digit. We then count how many places we move the decimal point to get from 1,322,000,000 to 1.322.
Moving the decimal point 9 places to the left gives us:
1.322 × 10^9
Thus, the correct answer is:
**1.322×10^9**
