- In mathematics, the logarithm is the inverse function to exponentiation. That means that the logarithm of a number x to the base b is the exponent to which b must be raised to produce x. For example, since 1000 = 10^3, the logarithm base 10 of 1000 is 3, or log10 (1000) = 3. The logarithm of x to base b is denoted as logb (x), or without parentheses, logb x, or even without the explicit base, log x, when no confusion is possible, or when the base does not matter such as in big O notation.

Israel in Egypt, HWV 54, is a biblical oratorio by the composer George Frideric Handel. Most scholars believe the libretto was prepared by Charles Jennens, who also compiled the biblical texts for Handel’s Messiah. It is composed entirely of selected passages from the Old Testament, mainly from Exodus and the Psalms.
