- 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.

The Canary Islands (/kəˈnɛəri/, Spanish: Canarias, Spanish: [kaˈnaɾjas]), also known informally as the Canaries, are a Spanish region, autonomous community and archipelago in the Atlantic Ocean. At their closest point to the African mainland, they are 100 kilometres (62 miles) west of Morocco. They are the southernmost of the autonomous communities of Spain. The islands have a population of 2.2 million people and are the most populous special territory of the European Union.
