WebJun 7, 2024 · How to Solve Logarithmic Equations Involving Same Bases - Simple Explanation. Learn how to solve Logarithmic and Exponential Equations with the Same … WebSometimes the terms of an exponential equation cannot be rewritten with a common base. In these cases, we solve by taking the logarithm of each side. Recall, since log (a) = log (b) log (a) = log (b) is equivalent to a = b, a = b, we may apply logarithms with the same base on both sides of an exponential equation.
