Logarithm
In mathematics, the logarithm of a number to a given base is the power or exponent to which the base must be raised in order to produce the number. For example, let us say we have the expression "four squared is equal to sixteen" or 4^2 = 16. When we try to find the logarithm of the number 16, we are trying to find the "power" by which the base (in this case it is four) is multiplied to produce it. In this case the logarithm of of the number 16 to the base four is two, or log_4 (16) = 2.
