WebSolve log2(8) = x. I can solve this by converting the logarithmic statement into its equivalent exponential form, using The Relationship: log 2 (8) = x 2 x = 8 But 8 = 23, so I can equate powers of two: 2 x = 2 3 x = 3 Note that this could also have been solved by working directly from the definition of a logarithm. 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.
