logxn
Logxn is a compact notation that is sometimes used to denote the logarithm of a number x with base n. In standard mathematical writing this quantity is usually written as log base n of x, log_n(x). The form logxn can appear in calculators, programming libraries, or informal text, but its meaning can vary by source, since some authors use log_x(n) to mean the logarithm of n with base x.
The function log_n(x) is defined for x > 0 with a base n satisfying n > 0 and n
Computing log_n(x) in practice often uses a more basic logarithm such as the natural log or base-10
Examples illustrate the concepts: log_2(8) = 3, since 2^3 = 8; log_{1/2}(4) = −2, since (1/2)^(−2) = 4. Logarithms are
