Answer:
Step-by-step explanation:
For this case we have the following expression:
(1)
And we want to find the value of ln K. If we apply natural log on both sides of the equation (1) we got:

Using the following property:
for x and y real numbers, x>0, y>0, then we have:

Now since the natural log and the exponentiation are inverse operations we have this:

And then the final expression for ln K is :
