Now, lets start with the equation:

Writing left side with logarithmic base e, we have:

We can now use the property shown below to make this into exponential form:

So, we write:

We recognize another property of exponentials:

So, we write:

Also, another property of natural logarithms is:

Now, we simplify:

This is the answer.
