Thus we can write 1 million in exponential notation as follows: 1,000,000 ϭ 1 ϫ 10 ϫ 10 ϫ 10 ϫ 10 ϫ 10 ϫ 10 ϭ 1 ϫ 106 Goldberg: Fundamentals of Chemistry, Fifth Edition 2. 1 Important Exponential Parts and Their Meanings In standard exponential notation, the coefficient is 1 or more but less than 10. 1 1 10 100 1000 1,000,000 1,000,000,000 One-billionth One-millionth One-thousandth One-hundredth One-tenth One Ten One hundred One thousand One million One billion Scientists generally report numbers in exponential notation with coefficients that have one and only one integer digit, and that digit is not zero.
1 Change 5445 minutes to seconds (s). A ratio or rate may be inverted (turned upside down) if the units that need to be canceled call for that. 50 per hour. 50 dollars In this case, the inverse of the rate of pay (the factor used previously to calculate total wages) is employed. Rates or ratios can be used either right side up or upside down; getting the units to cancel properly will indicate which form to use. 50) stays with the proper unit (dollars). 0 miles per hour (mph). 67 to cents as an example.
