    And if you are confused why 1/i = -i, a simplified algebraic way of looking at it is

    Knowing i^2 = -1, divide by sides by i and then
    i^2/i = -1/i
    i= -1/i
    -i = 1/i

    Your book is wrong.

    x^(3/2) + 8x^(1/2) + 16x^(-1/2) = 0

    has a solution at x = -4


    Substituting -4 into the left side of equation we get

    (-4)^(3/2) + 8*(-4)^(1/2) + 16*(-4)^(-1/2)
