Full Answer

The natural logarithm function is the log function to the base of e, rather than to the base 10, as with the function log(x). The natural log of e can be solved using the natural log's exponential properties, where the ln(e^x) is always equal to x when x is a number greater than zero. The reverse of this rule is expressed as e^ln(x) = x.
