Exponent Quotient Rule

I know that (a^b)/(a^c) = a^(a - c). We keep the same base and subtract exponents.

Can I say that (10^(x + y))/(10^(x - y)) = 10^(x + y -(x - y))?

If so, then 10^(x + y - x + y) leads to 10^(y + y).

I finally get 10^(2y).

You say?

Thanks. You know, reviewing basic material before moving on with the textbook. The best thing about self-study is the fact that I don't need to rush through th material for an exam.
