A number or symbol placed as a superscript to a number, expression, or quantity that represents the power to which it is to be raised. That is, the number of times that number, expression, or quantity is to be multiplied by itself. Exponents follow simple laws:

• Multiplication: x^a x^b = x^a+b

• Division: x^a / x^b = x^a‒b

• Power of a power:(x^a)^b = x^ab

Where the exponent is zero, the number or variable is equal to 1, i.e x⁰ = 1.
