    Negative Indices

    Having some trouble with the following 3 indices, any help, or advice would be appreciated. The question asks: Write these using negative indices.

    4 (Four divided by X squared)
    x2

    a2 (a squared divded by b cubed)
    b3

    3 (3 divided by y to the power of 5)
    y5

    Once again any help or advice would be appreciated.
