Below are sample questions representative of the exercises included on this worksheet and related 8.35 Estimating and Interpreting Magnitude with Scientific Notation skill assessments:

Problem 1Difficulty: Hard
Use the numbers in scientific notation to fill in the blank: Planet A = 4.2 x 1018 grams; Planet B = 1.4 x 1013 grams. Planet A is ___ times Planet B.
Solution & Explanation:Compare the coefficients and the powers of 10: (4.2 / 1.4) x 10^(18 - 13) = 3 x 105 = 300000. So Planet A is 300000 times as much as Planet B.
Problem 2Difficulty: Hard
Compare these two quantities: Total O is 1.125 x 10^-6, and Total P is 4.5 x 10^-9. Which comparison is correct?
ATotal O is 2500 times as much as Total P.
BTotal P is 250 times as much as Total O.
CTotal O is 250 times as much as Total P.
DTotal O is 25 times as much as Total P.
Solution & Explanation:Compare the coefficients and the powers of 10: (1.125 / 4.5) x 10^(-6 - -9) = 0.25 x 103 = 250. So Total O is 250 times as much as Total P.
Problem 3Difficulty: Hard
Use scientific notation to compare Sensor array A, 3 x 104 meters, and Sensor array B, 9 x 107 meters. Which sentence is true?
ASensor array B is 300 times as much as Sensor array A.
BSensor array B is 3000 times as much as Sensor array A.
CSensor array B is 30000 times as much as Sensor array A.
DSensor array A is 3000 times as much as Sensor array B.
Solution & Explanation:Compare the coefficients and the powers of 10: (9 / 3) x 10^(7 - 4) = 3 x 103 = 3000. So Sensor array B is 3000 times as much as Sensor array A.
