Additional Properties of Exponents For any real number a > 0, a 0, the following statements are true: (a) ax is a unique real number for each real number x. (b) ab = ac if and only if b = c. (c) If a > 1 and m < n, then am < an. If 0 < a < 1 and m < n, then am > an. If a > 0, a 1, then f (x) = a^x defines the exponential function with base a.
