WebMay 25, 2024 · Sometimes 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) is equivalent to a = b, we may apply logarithms with the same base on both sides of an exponential equation. WebJul 17, 2024 · The natural logarithm of 1 is zero. For example, if 1 is the power and 0 is the exponent, then you have e 0 = 1. This obeys the laws of exponents discussed in Section 2.4 of this chapter. The natural logarithm of any number greater than 1 is a positive number. For example, the natural logarithm of 2 is 0.693147, or e 0.693147 = 2.
