The exponential function f with base a is denoted by , where , and x is any real number. The function value will be positive because a positive base raised to any power is positive. The exponential equation could be written in terms of a logarithmic equation as . The exponential equation can be written as the logarithmic equation . Since logarithms are nothing more than exponents, you can use the rules of exponents with logarithms.
Logarithmic functions are the inverse of exponential functions.
