Step 1 :

\

L\"\"Hospital\"\"s Rule :

\

 If the value of limit is indeterminate form of type \"\" or \"\", then

\

\"\"

\

Step 2 :

\

The expression is  \"\"

\

Evaluation of the limit :

\

\"\"

\

Step 3 :

\

Since \"\" use L\"\"Hospital\"\"s rule.

\

\"\"

\

Thus,  \"\"

\

Solution :

\

\"\"
