Solving an Exponential Equation by Rewriting with a Common Base
To solve an exponential equation by rewriting it with a common base, follow a systematic four-step procedure. Step 1: Write both sides of the equation with the same base, if it is mathematically possible. Step 2: Write a new equation by setting the exponents from both sides equal to each other, utilizing the one-to-one property of exponential functions. Step 3: Solve the newly formed equation for the variable using standard algebraic techniques. Step 4: Check the solution by substituting it back into the original exponential equation to ensure it produces a true statement.
