You may want to review easier exponential equations and logarithms first.

With logarithms, you can solve exponential equations that you couldn't have solved before. For example, suppose you have to solve 14−1 ⁄ 3 * x + 4 = 11. Then, using logarithms, you know −1 ⁄ 3 * x + 4 = log14 11, so the answer is x = −3(log14 11 − 4).
