12. Which of the following lists are ordered from greatest to least? Select all the correct answers. A B 4.0times 10^-7, 2.0times 10^2, 3.0times 10^6, 5.0times 10^12 3.0times 10^7, 3.0times 10^6, 3.0times 10^2, 3.0times 10^-7 D 1.8times 10^9, 1.5times 10^5, 1.4times 10^-5, 1.9times 10^-8

To determine which lists are ordered from greatest to least, we need to compare the values in each list.Let's analyze each option:A: - is the smallest value.- is larger than but smaller than the other values.- is larger than but smaller than .- is the largest value.B: - is the smallest value.- is larger than but smaller than the other values.- is larger than but smaller than .- is the largest value.D: - is the smallest value.- is larger than but smaller than the other values.- is larger than but smaller than .- is the largest value.Based on the analysis, the correct answers are:ABD
