Logarithmic Functions – Solving Logarithmic Equations

Solving Logarithmic Equations

For FREE access to this lesson, select your course from the categories below.

The problems in this lesson involve solving logarithmic equations. To learn how to solve logarithmic equations, we start by simply converting the equation from logarithmic to exponential form. For example, when solving logarithmic equations such as 'log base x of 144 equals 2,' we switch from logarithmic to exponential form, to get x^2 = 144, or x = plus or minus 12. However, it's important to understand that the base of a log cannot be negative, so the answer to this logarithmic equation is x = 12. In this lesson, no logarithmic equation calculator is required, and a self-test serves as an interactive logarithmic equations worksheet.
