Full solution stays hidden until you ask for it.
1. Identify argument and base.
2. Write log_b(a)=ln(a)/ln(b).
3. Evaluate exactly when powers match or approximate as requested.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
