Answer:

Step-by-step explanation:
For this case we have the following expression:

We need to remember that the natural log and the exponentiation with the base the euler number e are inverse operations, and if we apply exponentiation on both sides of the equation we got this:

We have the identity operator for this 

And that would be our final answer for this case.
