The natural logarithm is often written as ln which you may have noticed on your calculator. lnx = log e x The symbol e symbolizes a special mathematical constant.
A natural logarithm is a logarithm that has a special base of the mathematical constant \ (e\), which is an irrational number approximately equal to \ (2.71\). The natural logarithm of \ (x\) is generally written as ln \ (x\), or \ (\log_ {e} {x}\). Natural Logarithms – Example 1: Solve the equation for \ (x\): \ (e^x=3\) Solution:

A formula using natural logarithms is the continuous compound interest formula where A is the final amount, P is the amount invested, r is the interest rate, and t is time. Example #1 : Find the value of $500 after 4 years invested at an annual rate of 9%
Definition 1: The logarithm with base 10 is called the _____ logarithm. o The base does not need to be shown when writing a common logarithm. o “log x” is understood to mean “log 10 x”. (You do not have to write the 10). o The LOG key on your calculator gives base 10 logarithms. Ex 1: Evaluate log 8 ylog 10
