"WebA logarithm is the power to which a number must be raised in order to get some other number (see Section 3 of this Math Review for more about exponents). For example, the base ten logarithm of 100 is 2, because ten raised to the power of two is 100: log 100 = 2 because 102 = 100 This is an example of a base-ten logarithm. " - Is dbm logarithmic
