Sullivan, 8 th ed. MAC1140/MAC1147 6.6: Logarithmic and Exponential Equations Logarithmic equations of the form log a x , where a is a positive real number 1. Exponential equations have terms of the form a x , a > 0, a 1. Remember that logarithms of negative numbers are not defined; therefore, solutions must be checked for extraneous solutions. Solve: 1. log 5 (x 2 + x + 4) = 2 2. 4 log 4 (x – 3) + log
