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.
