  1. Actually I only need help with the second problem,and the 7th problem,

    Simplify. mn^-4/p^0q^-2

    Evaluate 1/2a^-4b^2 for a=-2 and b=4.

  2. p^0 = 1, so

    mn^-4/p^0q^-2 = (m/n^4) / (1/q^2) = mq^2/n^4

    1/(2 (-2)^-4 (4)^2)
    1/(2 (1/16) (16))
    1/2

    Note that (-2)^4 = (-2)(-2)(-2)(-2) = +16
