Logarithm meaning
For a number x, the exponent by which a given base number must be raised in order to obtain the power x. Written log _bx. For example, log ₁₀1000=3 because 10³=1000 and log ₂16=4 because 2⁴=16.

The function that assigns to y its logarithm is called logarithm function or logarithmic function (or just logarithm).
When this set is plotted on a logarithmic scale it has one-dimensional translational symmetry : adding or subtracting the logarithm of two to the logarithm of one of these numbers produces the logarithm of another of these numbers.
A maximum of the likelihood function occurs at the same parameter-value as a maximum of the logarithm of the likelihood (the "log likelihood"), because the logarithm is an increasing function.
A multiplicative magic square can be derived from an additive magic square by raising 2 (or any other integer) to the power of each element, because the logarithm of the product of 2 numbers is the sum of logarithm of each.
Chief among them are: the logarithm of the number one is zero; and the logarithm as x approaches zero from the right is negative infinity.
For elliptic-curve-based protocols, it is assumed that finding the discrete logarithm of a random elliptic curve element with respect to a publicly known base point is infeasible: this is the "elliptic curve discrete logarithm problem" or ECDLP.
Natural logarithm Consider the natural logarithm function mapping the real numbers to themselves.
Piecewise linear approximation to exponential and logarithm Integers reinterpreted as floating point numbers (in blue, piecewise linear), compared to a scaled and shifted logarithm (in gray, smooth).
Product, quotient, power and root The logarithm of a product is the sum of the logarithms of the numbers being multiplied; the logarithm of the ratio of two numbers is the difference of the logarithms.
Their solution generated the requisite "hyperbolic logarithm" function having properties now associated with the natural logarithm.
The logarithm must be taken to base since the two terms following the logarithm are themselves base-e logarithms of expressions that are either factors of the density function or otherwise arise naturally.
The logarithm of a non-positive real is not a real number, so the natural logarithm function doesn't associate any real number in the codomain with any non-positive real number in the domain.
The quantity ln(a) is the natural logarithm of a, i.e. its logarithm to base "e".
This area equals the natural logarithm of 6. The graph of the natural logarithm function shown earlier on the right side of the page enables one to glean some of the basic characteristics that logarithms to any base have in common.
This exponential function can be inverted to form a complex logarithm that exhibits most of the properties of the ordinary logarithm.
