Making Exponential Expressions and Operations More Compatible
An exponential expression consists of a base and a power. The general format of an exponential expression is bn, where b is the base and n is the power or exponent. The base, b, has to be a positive number, and the power, n, is a real number. Positive powers, negative powers, and fractional powers all have special meanings and designations.
