In mathematics, the logarithm of a given number to a given base is the power or exponent to which the base must be raised in order to produce the given number. For example, the logarithm of 1000 to the common base 10 is 3, because 10 raised to the power of 3 is 1000; the base 2 logarithm of 32 is 5 because 2 to the power 5 is 32. The logarithm of x to the base b is written logb(x) or, if the base is implicit, as log(x). So, for a number x, a base b and an exponent y, » mbox However, it can als… (More on Logarithm)
