Full solution stays hidden until you ask for it.
1. Choose benchmark powers near the argument.
2. Place the argument between those powers.
3. Convert power exponents into a log-value interval.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
