There are many applications of exponential and logarithmic functions. In most cases, the expressions in the equations are difficult to write in the same base, so you need to find a way to solve these equations algebraically. In Try This 1 you will review how to solve equations with the same base. Later in the lesson you will learn how to solve equations that can’t be easily rewritten with the same base.
Use the equation 2 log x = log 25 to answer the following questions.
