#### 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 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.
