scientific notation example would be if you have 10000 in scientific notation it would be 1x10^4     <-- the 4 as how many 0's after 1

In scientific notation the numbers are written in the form: M x 10^N 
Where M is a a number in the range: 1 <= M < 10. M can be an integer or a decimal. 
N is an integer.

Regarding usage, let us say you are asked to multiply 5000 and 80000. 

First put 5000 in scientific notation: 5000 = 5 x 10^3 
Put 80000 in scientific notation:    80000 = 8 x 10^4 

5000 x 80000 = 5 x 10^3 * 8 x 10^4 
                       = 40 x 10^(3 + 4) = 40 x 10^7 = 4 x 10^8
