WebApr 19, 2024 · Type 1. In this type, the variable you need to solve for is inside the log, with one log on one side of the equation and a constant on the other. Turn the variable inside the log into an exponential equation (which is all about the base, of course). For example, to solve log 3 x = –4, change it to the exponential equation 3 –4 = x, or 1/81 = x. WebWhen I take the log of both sides of an equation, I can use any log I like (base-10 log, base-2 log, natural log, etc), but some are sometimes more useful than others. Since the base in the equation "2 x = 30" is "2", I might try using a base-2 log: log 2 (2 x) = log 2 (30) imark showcase
