## anonymous 5 years ago How do I simplify the expression 9^6/9^-3

1. anonymous

you have:$\frac{9^6}{9^{-3}} = 9^6 . 9^3 = 9^9$ ^_^

2. anonymous

approx = 387420489 :)

3. anonymous

Why don't you multiply 9*9??

4. anonymous

when you divide with same base...you subtract the exponents...you add when you mutliply

5. anonymous

keep base...that is the rule

6. anonymous

no need as long as you can change the sign of the power :) to make your life easier ^_^
