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).

Answer 1

Exponential equation:

3^x = 27

Work:

x = log3(27)

Mistake:

x = log3(27) + 1

Corrected Work:

x = log3(27)

Answer 2

27 = 3^3 or mistakenly 27 = -3^3
so x = +3
