An integer exponent is the number of times that a number is multiplied by itself.
For example: if the exponent of a is 3, then it represents the number a3 = a*a*a.
The laws of exponents can be extended to arrive at definitions of negative exponents [a-3 = 1/a3] and fractional exponents [a1/3 is the cube or third root of a]. These definitions can be further extended to exponents that are Irrational Numbers, or even complex number.
