Step-by-step solution

To solve this problem, we'll follow these steps:

  • Step 1: Apply the mathematical property using the quotient rule for logarithms.
  • Step 2: Simplify the expression into the desired format.

Now, let's work through each step:
Step 1: Given the expression log89alog83a\frac{\log_8 9a}{\log_8 3a}, we can directly apply the quotient rule for logarithms, which tells us that logbMlogbN=logNM\frac{\log_b M}{\log_b N} = \log_N M.
Step 2: Applying this formula, we find that log89alog83a=log3a9a\frac{\log_8 9a}{\log_8 3a} = \log_{3a} 9a.

Therefore, the solution to the problem is log3a9a \log_{3a} 9a .
