(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. 
No it ended up looking wierd when I submited, sorry.Here is the real question (3.2 x 10^5) (2 x 10^3)

(2 x 10^5)
