Explanation
## Step 1: Rationalizing the Numerator### To evaluate the limit, we'll rationalize the numerator by multiplying the expression by
. This will help simplify the expression and eliminate the indeterminate form
as
approaches 0.## Step 2: Simplifying the Expression### After multiplying, the numerator becomes
, and the denominator becomes
. We can then cancel out the
terms in the numerator and denominator, leaving
.## Step 3: Evaluating the Limit### Now, we can substitute
into the simplified expression:
.
