WebThe equations with logarithms on both sides of the equal to sign take log M = log N, which is the same as M = N. The procedure of solving equations with logarithms on both sides of the equal sign. If the logarithms have are a common base, simplify the problem and then rewrite it without logarithms. WebMay 17, 2015 · There are other equations similar to this which are products and sums of different expressions e.g., exponentials, quadratics etc. which can be solved on their own but when together are much harder (for me) to solve, e.g., $$ 2^nn+c=0\\ 2^n+n=0\\ 2^xx^2=0 $$ I could go on forever, but how are these equations that seem impossible to solve solved?

Exponential equations come in two forms. In one case, it is possible to get the same base on each side of the equation. When this happens, there is a rule that says if the bases are the same, then the exponents must be the same also. If a > 0 and a 1, then a b = a c is true if and only if b = c. david smith of thiensville wi

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.
