Answer:
Option C, D, E
Step-by-step explanation:
To find : Which pairs of numbers in scientific notation shows one number that is about 20 times as great as the other number?
Solution :
We divide large number by smaller number to get the required answer,
A) [tex]\frac{2.01\times 10^7}{4.25\times 10^6}=4.7294\approx 4[/tex]
B) [tex]\frac{5.97\times 10^4}{3.12\times 10^3}=19.1346153846\approx 19[/tex]
C) [tex]\frac{4.91\times 10^6}{5.09\times 10^3}=9365.4033\approx 9365[/tex]
D) [tex]\frac{8.21\times 10^{-3}}{4.13\times 10^{-4}}=19.8789\approx 20[/tex]
E) [tex]\frac{6.22 \times 10^{-7}}{2.94\times 10^{-8}}=21.156462585\approx 21[/tex]
Option C, D and E pairs of numbers in scientific notation shows one number that is about 20 times as great as the other number.
