How do you solve #ln x=9#?
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 x, we are just left with x on the left side since
Now, we have to do the same thing on the right side and raise e to the ninth power like this:
When you do that calculation, you obtain an approximate value of 8,103.
