Question

Order 34 x 10^2, 1.2 x 10^7, 8.11 x 10^-3, and 435 from least to greatest.

Answer 1

8.11x10^(-3), 435, 34x10^2, 1.2x10^7 :-)
34x10^2 can be rewritten as 3.4x10^3, while 435 is 4.35x10^2

Answer 2

yeah, getting all the 10 spots to the exponent would make it simpler

Answer 3

to the "same" exponent

Answer 4

Sort[{34 * 10^2,1.2 *10^7,8.11 * 10^-3, 435}]=\[\{0.00811,435,3400,1.2\times 10^7\} \]
