    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?

    \4^3 (\frac{3}{4})^2 = 4^3 \frac{3^2}{4^2} = \frac{4^3.3^2}{4^2} = 4.3^2 = 36
