Which of the following is NOT a strategy that is often used to solve logarithmic equations? a. Express the equation in exponential form and solve the resulting exponential equation. b. Simplify the expressions in the equation by using the laws of logarithms. c. Represent the sums or differences of logs as single logarithms. d. Square all logarithmic expressions and solve the resulting quadratic equation.
