  1. your numbers were probably written as
    2.5 x 10^7
    which means 2.5 x 10000000 , notice 7 zeros from 10^7
    = 25 000 000 --> 25 million

    do the same with the other numbers and you will be able to compare their sizes.

    8.57 x 10^-4
    = 8.57 x 1/10^4
    = 8.57 x 1/1000 -----> count the zeros in the denominator
    = .000857 -----> how many places to the left has the decimal moved?
    does that give you any hints for quick solutions to these kind of problems?
