Full solution stays hidden until you ask for it.
1. Divide by the leading coefficient.
2. Take logarithms of both sides.
3. Use the power rule to bring down the exponent.
4. Solve for the variable and check context units.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Taking logs before isolating the exponential factor.
