  1. 1B ok

    2B 6-2=4, not 6/2 = 3
    Just as in #1 you added powers when multiplying, you subtract powers when dividing.

    3D
    5^-3 = 1/5^3 = 1/125
    You just dis 1/(5*3)

    4B
    Think of division, and subtracting powers:

    5^3/5^3 = 5^(3-3) = 5^0
    x^0 = 1 for any nonzero value of x.

    5A,B,D
    Not E, since (y^4)(y^1) = y^(4+1) = y^5
    You did (y^4)(1) = y^4

  2. 1. (y^4)(y^3) = y^7

    2. Y^6 / Y^2 = Y^4

    3.5-^3 = 1/125

    4. 15^0= 1

    5. Y^4 = (y^2) (y^2), Y^6/y^2 AND Y^9/ Y^5.
    THESE ARE A 100% CORRECT
