9^12/9^3

2. anonymous

A) 9^15 B) 9^4 C) 9^9 D) 1^4

So you have $$\large\frac{9^{12}}{9^3}$$. Do you know HOW to divide exponents?

4. anonymous

No

5. BloomLocke367

well, just when you multiply two or more exponents, all you have to do is add them together (as long as the base is the same) so when you divide two or more exponents, you subtract. For example: $$\large\frac{x^\color{red}{7}}{x^\color{red}{5}}=x^2$$. Do you understand that?

6. BloomLocke367

What would you get from your problem?

7. BloomLocke367

subtract 3 from 12
