what is a base and what is an exponent
An exponent is a quantity representing the power to which some other quantity is raised. Exponents do not have to be numbers or constants; they can be variables. They are often positive whole number s, but they can be negative number s, fractional number s, irrational number s, or complex number s.
The zero exponent rule is one of the rules that will help you simplify exponents. Let's first define some terms as they relate to exponents. When you have a number or variable raised to a power, the number (or variable) is called the base, while the superscript number is called the exponent, or power.
