China has a population of approximately 1,322,000,000 people. express this number in scientific notation.

In scientific notation, you must move the "invisible decimal point" until there is a one-digit number, sometimes followed by a decimal of more numbers. Then, how ever many digits you had to move it is the exponent to the number 10.
Example:
1200.
120.0
12.00
1.200
Since the decimal had to move 3 places, the scientific notation of this is:
1.2 • 10^3

In this question, the decimal must move 9 places left before resulting in 1.322.
So the answer, in scientific notation, is 1.322 • 10^9.
