(3.2 x 10^5) (2 x 10^-3)
-------------------------
(2 x 10^-3)
I got 1.6 x 10^5 like this,
(3.2 x 10^5) (2 x 10^-3)
------------ x -----------
(2 x 10^-5) (2 x 10^-5)

(3.2 x 10^5) (2 x 10^-3)
------------ x
(2 x 10^-5)

(3.2 x 10^5)
------------ > 3.2 10^5
(2 x 10^10) --- -----
2 10^10
1.6 x 10^5
Is that right?

    No it is not right. Your work is just plain wrong. And finally, I am not certain exactly what the original problem is. The first line was

    (a * b)/b as I read it...
    (3.2 x 10^5) (2 x 10^-3)
    -------------------------
    (2 x 10^-3)
    and the answer to that is a, or
    3.2 x10^5

    So I really don't understand what you are trying to do.
