I introduced the topic of solving logarithmic and exponential equations to Matthew. I showed him examples of how to modify the appearance of the bases on either side to be the same. Then I explained that if the bases were the same in an equation, the exponents must be equal so the equation is rewritten with only the exponents set equal to each other and then it is solved for the variable. I also showed him how to take the logarithm of both sides of an equation to solve for a variable. There was no assignment.
