Simplify 10 to the 6 power over 10 to the negative 3

To simplify 10^6/10^-3 you first need to get rid of the negative exponents so you bring up 10^-3 so it becomes:

10^6x10^3 then all that you have to do is add the exponents since the bases for both are the same.

So the final answer is:

10^9

Or in other words:

10 to the power of 9
