This Video (based on our math blog and class recordings) outlines a step-by-step solution to a logarithmic equation where the unknown variable, x, appears in both the base and as an exponent. It begins by applying the power rule of logarithms to simplify the initial expression. Subsequently, the equation is further simplified by dividing both sides by x, assuming x is not zero. The final steps involve converting the logarithmic expression into its exponential form and then solving for x, while also explaining the constraints on the base of a logarithm that eliminate extraneous solutions. The overall aim is to illustrate a common approach to solving such logarithmic problems efficiently.
