Logarithmic
Functions
2 c) Find the value of
ln e5. {Suggestion: Let y = ln e5. Find the value of y
by rewriting this logarithmic equation in exponential form and
then finding y.}
| y = logax if and only if x = ay | Recall the definition of the logarithm of x with a base of a. |
| y = y a = e x = e 5 |
Identify the values of y, a, and x in the equation y = ln e 5 . |
| Show work. | Using these values for y, a and x, rewrite the logarithmic equation in exponential form. |
