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 = log_{14}
11, so the answer is *x* = −3(log_{14} 11
− 4).
