MAC 1140-- Logarithmic Equations – Section 4

To solve logarithmic equations symbolically use one of the following methods. Always remember that in y = logb x, b >0, and x>0. So check for extraneous solutions. A. If there is . non-logarithmic term, isolate the log term. Write the equation in exponential form. Then solve the exponential equation. 1. log3 (x – 7) = 5 2. log3 = x 3. ................
