Thread: Simplify using the exponent laws.

Hi guys,

that is the task = Simplify using the exponent laws. Show the steps in your solution. Find the value of the power (evaluate).

1. (2^3) (3^2) (2^5)
my answer:
= (2^8) (3^2)
= (256) (9)
= 2304

Is that right?

2. (2^5) (3^4)
-----------
(3^2)
my answer:
= (2^5) (3^2)
= (32) (9)
= 288

Is that right?

3. 4^3 (3/4)^2
my answer:
= 4^3 (3^2/4^2)
= 64 9/16
= 64.5625

Is that right?

First two are correct.
