Hidden until you reveal it.
Exponential base must be positive and not equal to 1; inverse may use logarithm notation.
Enter your answer
Your answer is equivalent to the expected form.

1. Write y as the exponential expression.
2. Divide by any coefficient multiplying the exponential term.
3. Use logarithm notation to solve for the exponent.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
