- Logarithm - Wikipedia
In mathematics, the logarithm of a number is the exponent by which another fixed value, the base, must be raised to produce that number For example, the logarithm of 1000 to base 10 is 3, because 1000 is 10 to the 3 rd power: 1000 = 103 = 10 × 10 × 10

A logarithm tells what exponent (or power) is needed to make a certain number, so logarithms are one of the inverse operations of exponentiation (the other one being roots)
- List of logarithmic identities - Wikipedia
In mathematics, many logarithmic identities exist The following is a compilation of the notable of these, many of which are used for computational purposes Trivial mathematical identities are relatively simple (for an experienced mathematician), though not necessarily unimportant The trivial logarithmic identities are as follows:
- History of logarithms - Wikipedia
The history of logarithms is the story of a correspondence (in modern terms, a group isomorphism) between multiplication on the positive real numbers and addition on real number line that was formalized in seventeenth century Europe and was widely used to simplify calculation until the advent of the digital computer
- Natural logarithm - Wikipedia
The natural logarithm of a number is its logarithm to the base of the mathematical constant e, which is an irrational and transcendental number approximately equal to 2 718 281 828 459 [1]
- Common logarithm - Wikipedia
In mathematics, the common logarithm (aka "standard logarithm") is the logarithm with base 10 [1] It is also known as the decadic logarithm, the decimal logarithm and the Briggsian logarithm

logarithm, the exponent or power to which a base must be raised to yield a given number Expressed mathematically, x is the logarithm of n to the base b if bx = n, in which case one writes x = log b n For example, 2 3 = 8; therefore, 3 is the logarithm of 8 to base 2, or 3 = log 2 8 In the same fashion, since 10 2 = 100, then 2 = log 10 100
- Complex logarithm - Wikipedia
A single branch of the complex logarithm The hue of the color is used to show the argument of the complex logarithm The brightness of the color is used to show the modulus of the complex logarithm The real part of log (z) is the natural logarithm of |z| Its graph is thus obtained by rotating the graph of ln (x) around the z -axis In mathematics, a complex logarithm is a generalization of
