WebSteps to solving logarithmic equations 1. Combine all the logarithms into one. 2. Two scenarios: i. \log_bM = \log_bN logbM = logbN → M=N M = N ii. \log_bM = N logbM = N → b^N = M bN =M 3. Plug the answer back into the original equation to make sure the inside of any logarithm is non-negative. Basic Concepts WebTo solve a logarithmic equations use the esxponents rules to isolate logarithmic expressions with the same base. Set the arguments equal to each other, solve the equation and check your answer. What is logarithm equation? A logarithmic equation is an equation that involves the logarithm of an expression containing a varaible.
