Hi guys,

That is the task: Simplify. Write each as a single power. Do not evaluate.

1. (3/5)^9 (3/5)^15

my answer:

= (3^9/5^9) (3^15/5^15)

= 3^24/5^24

Is that the right answer?

2. (-Q)^2 (-Q)^5 (-Q)

my answer:

= (-Q^2) (-Q^5) (-Q)

= -Q^8

Is that the right answer?

3. (-2)^7

-------

(-2)^3

my answer:

= (-2)^4

Is that the right answer?
