![]() ![]() Exponential equations have the variable in an exponent. For example: 42x - 1 = 65x Logarithmic equations involve logarithms. For example: 3log2(x - 1) = log28 + 17 There are two main types of problems in each category. We'll show you examples of how to solve each type. Exponential Equations Logarithmic Equations Logarithmic equations may have answers which won't work, called extraneous answers, because they would involve doing the log of zero or a negative number. This means that all possible solutions must be checked in the original equation to ensure that this doesn't happen. |
