Logarithms. The mathematics of logarithms and exponentials occurs naturally in many branches of science. It is very important in solving problems related to growth and decay. The growth and decay may be that of a plant or a population, a crystalline structure or money in the bank.

Using the laws of logarithms this equals 23log2 2. which equals 23 or 8, since log2 2 = 1. We see that raising the base 2 to the logarithm of a number to base 2 results in the original number. So raising a base to a power, and finding the logarithm to that base are inverse operations.
