logarithm

noun

Mathematics

The power to which a base, such as 10, must be raised to produce a given number. If n^x = a, the logarithm of a, with n as the base, is x; symbolically, log _n a = x. For example, 10³ = 1,000; therefore, log₁₀ 1,000 = 3. The kinds most often used are the common logarithm (base 10), the natural logarithm (base e ), and the binary logarithm (base 2).

Origin of logarithm

New Latin logarithmus Greek logos reason, proportion ; see leg- in Indo-European roots.Greek arithmos number ; see ar- in Indo-European roots.
