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) ![\frac{2.01\times 10^7}{4.25\times 10^6}=4.7294\approx 4](https://tex.z-dn.net/?f=%5Cfrac%7B2.01%5Ctimes%2010%5E7%7D%7B4.25%5Ctimes%2010%5E6%7D%3D4.7294%5Capprox%204)
B) ![\frac{5.97\times 10^4}{3.12\times 10^3}=19.1346153846\approx 19](https://tex.z-dn.net/?f=%5Cfrac%7B5.97%5Ctimes%2010%5E4%7D%7B3.12%5Ctimes%2010%5E3%7D%3D19.1346153846%5Capprox%2019)
C)
![\frac{4.91\times 10^6}{5.09\times 10^3}=9365.4033\approx 9365](https://tex.z-dn.net/?f=%5Cfrac%7B4.91%5Ctimes%2010%5E6%7D%7B5.09%5Ctimes%2010%5E3%7D%3D9365.4033%5Capprox%209365)
D) ![\frac{8.21\times 10^{-3}}{4.13\times 10^{-4}}=19.8789\approx 20](https://tex.z-dn.net/?f=%5Cfrac%7B8.21%5Ctimes%2010%5E%7B-3%7D%7D%7B4.13%5Ctimes%2010%5E%7B-4%7D%7D%3D19.8789%5Capprox%2020)
E) ![\frac{6.22 \times 10^{-7}}{2.94\times 10^{-8}}=21.156462585\approx 21](https://tex.z-dn.net/?f=%5Cfrac%7B6.22%20%5Ctimes%2010%5E%7B-7%7D%7D%7B2.94%5Ctimes%2010%5E%7B-8%7D%7D%3D21.156462585%5Capprox%2021)
