Mara solved an exponential equation by using logarithms. This is her work. 1. 7 . 3^x =189 2. 3^x =27 3. Log_3(3^x) =log_3 27 4. log _3 3=9 5. X . 1 =9 6. X=9

1. Review Mara's work in steps 3 and 4. (Hint: There is one mistake in those steps.) a. Be sure to explain what she did and why it was correct or incorrect for Step 3.

b. Be sure to explain what she did and why it was correct or incorrect for Step 4.

c. Provide Mara with feedback on what the mistake was and how to fix it.

2. Create your own example of solving an exponential equation, with work shown, that includes at least one mistake that a student could easily make (for example: a common calculation error, or a forgotten or misordered step).

Make sure to answer question 1 and 2
