If  then the value of   is
,

The correct answer is: 5

In this question we are given ,  and . We have to find 
Step1: Putting the value of the limit
By putting the value of the limit in the expression, we get, both numerator and denominator as zero. That is  form.
Step2: Using L'Hôpital's rule
By differentiating both numerator and denominator we get,


By putting the value of limits we get,

=>
Hence, the value of the limit is
