This is a great activity to bridge the gap between the two methods of solving exponential equations. If students already know one method this would be a great introduction to learning the other method. Additionally, it could be used as a recap of both methods to solidify student understanding and develop their procedural fluency in solving exponential equations.

Students sort 16 equations into two categories: Equations that can be solved without logarithms (by rewriting with a common base) and equations that can be solved with logarithms. Then they create a mini poster showing how to solve each type of problem

Explain each step in solving a simple equation as following from the equality of numbers asserted at the previous step, starting from the assumption that the original equation has a solution. Construct a viable argument to justify a solution method.
Use the properties of exponents to transform expressions for exponential functions. For example the expression 1.15 to the 𝘵 power can be rewritten as ((1.15 to the 1/12 power) to the 12𝘵 power) is approximately equal to (1.012 to the 12𝘵 power) to reveal the approximate equivalent monthly interest rate if the annual rate is 15%.
