Step-by-step explanation:
We need to first simplify the expression using rationalization(i.e. if a square root term exists in the denominator, then multiply and divide the whole expression by the denominator(but the change the sign of its middle term))
here, we need to find:
first we'll rationalize our expression:
this is our simplified expression, now we can apply our limits:
the limit does exists and it is 2.
