4.

Step-by-step explanation:

We are asked to find the value of expression at .

First of all, we will find the derivative of the given expression using "Quotient Rule of Derivatives" as shown below:

Therefore, our required derivative is .

Now, we will substitute in our derivative to find the required value as:

Therefore, the value of expression at is 4.
