Solution
To solve this expression step by step:
Step 1: Simplify the numerator using logarithmic properties
The numerator is:
Step 1.1: Rewrite in terms of base 3
Since , we use the change of base property:
Now, substitute into the numerator:
Step 1.2: Combine terms under base 3
The first term, , can be written as:
Thus, the numerator becomes:
Combine like terms involving :
So the numerator simplifies to:
Step 2: Simplify the denominator
The denominator is:
Using the change of base formula:
Recall that , so:
Step 3: Combine numerator and denominator
The expression becomes:
Factor out the negative sign in the denominator:
Step 4: Simplify further
Use the property in the denominator:
Final Answer:
