I havent taken math for years so please help me out. The problem is:

Using scientific notation, evaluate:

(4 x 10^8)^3 divided by (5 x10^-6)^2

Do I just convert this to 40 x 10^11 divided by 50 x 10^-4?

If so..

then I divide 40 by 50, which is .8

So we got .8 x 10^7 as the answer.

Am I doing this right? thanks.
