Step-by-Step Solution

To solve this problem, we'll simplify the given expression log9e2log9e\frac{\log_9e^2}{\log_9e} using logarithmic rules:

Step 1: Apply the power rule of logarithms:
The numerator log9e2\log_9e^2 can be rewritten using the power rule: log9e2=2log9e\log_9e^2 = 2 \cdot \log_9e.

Step 2: Substitute and simplify the fraction:
Substitute the expression from Step 1 into the original problem:
log9e2log9e=2log9elog9e\frac{\log_9e^2}{\log_9e} = \frac{2 \cdot \log_9e}{\log_9e}.

Step 3: Cancel common terms:
Since log9e\log_9e appears in both the numerator and the denominator, it cancels out, leaving:
2log9elog9e=2 \frac{2 \cdot \log_9e}{\log_9e} = 2 .

Therefore, the solution to the problem is 2\boxed{2}.
