    Let n = any number

    We say n^(1) = n.

    Why is this the case?

    recall definition of exponent

    [​IMG] The exponent of a number says how many times to use that number in a multiplication.

    In this example: 8^2 = 8 × 8 = 64
    (The exponent "2" says to use the 8 two times in a multiplication.)

    in your case n^(1) = n*1=n (The exponent "1" says to use the n one time in a multiplication.)
