Math Problem Statement
Find the limit using lhopitals and logarithms
Solution
To find the limit
using L'Hôpital's Rule and logarithms, we can proceed with the following steps:
Step 1: Rewrite the Expression with Logarithms
Set . Taking the natural logarithm on both sides, we get: Now, our goal is to find:
Step 2: Simplify the Logarithmic Term
We can simplify as follows: Then,
Step 3: Use a Taylor Expansion (for Small Terms)
For large , . Therefore,
Step 4: Take the Limit
Now we need to compute Dividing the numerator and denominator by , we get:
Step 5: Interpret the Result
Since as , we have .
