Problem 41 of 7
Solve exponential equation e^(-x) = 3 with natural logarithms.
Using a hint is okay. It just tells the trainer to give you a little more review.
Hidden until you reveal it.
apply ln to both sides and divide.
Hidden until you reveal it.
Apply ln to both sides and divide for continuous growth or decay forms.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Isolate the e-power if needed.
2. Apply natural log to both sides.
3. Use ln(e^u)=u.
4. Solve for the variable.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Using common log incorrectly without equivalent change-of-base handling.
