You move the decimal nine places to the left to get a number between one and ten. In scientific notation: 3.482 x 10^9 Then you multiply that number by ten to the ninth power since you moved the decimal nine places to the left. Another example: 534,000,000 In scientific notation, it would be: 5.34 x 10^8 because you move the decimal eight places to the left to get a number between one and ten.
