Answer:
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.
