WebA logarithm function is defined with respect to a “base”, which is a positive number: if b denotes the base number, then the base-b logarithm of X is, by definition, the number Y such that bY = X. For example, the base-2 logarithm of 8 is equal to 3, because 23 = 8, and the base-10 logarithm of 100 is 2, because 102 = 100.
