How do you solve #ln4x=1#?
1 Answer
Explanation:
Let's use the diagram below:
This photo tells us that the natural log (ln) and the exponential function (
In our case if we raise e to the ln 4x, we are just left with 4x on the left side since
Now, we have to do the same thing on the right side and raise e to the first power like this:
When you do that calculation, you obtain an approximate value of 2.72 on the right side:
Now divide both sides by four in order to solve for x:
Therefore,
