To express the population of China, which is approximately 1,322,000,000 people, in scientific notation, you would convert it to the form \( a \times 10^n \), where \( 1 \leq a < 10 \) and \( n \) is an integer.
1,322,000,000 can be rewritten as:
- Move the decimal point 9 places to the left (since there are 9 digits to the left of the first non-zero digit, which is 1), so it becomes 1.322.
Thus, in scientific notation, it is:
\[ 1.322 \times 10^9 \]
So the correct response is:
1.322×10^9 (1 point 3 2 2 times 10 to the 9th power)
