We can use the idea of solving a power equation to find the base of a natural log. Recall the natural log (
. You should end up with
Change this to
. Convert your equation from log form to exponent form and solve for the base. Write your answer out to five decimal places.
This number you just found is called
, which is the base of natural log. The number is an irrational number which is very important in mathematics. You will learn more about this number later in chapter 8.
