How to solve logarithmic functions
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.
