(2.7182818…) is the base of the natural system oflogarithms(ln). By definitionxis alogarithm, and there is thus a logarithmic function that is the inverse of the exponential function (seefigure). Specifically, ify=ex, thenx= lny. The exponential function is also defined as the sum of ...
Logarithm definition: the exponent of the power to which a base number must be raised to equal a given number; log. See examples of LOGARITHM used in a sentence.
Initially, a mathematician named John Napier introduced logarithms for making calculations in a simple way and this concept is quickly adopted by other scientists, engineers, etc.Here is the mathematical definition of logs.Logs DefinitionA logarithm is defined using an exponent....

Define logarithm. logarithm synonyms, logarithm pronunciation, logarithm translation, English dictionary definition of logarithm. n. Mathematics The power to which a base, such as 10, must be raised to produce a given number. If nx = a, the logarithm of
from the definition of the logarithm of the number b to the base a, we have the identity \(\begin{array}{l}{{a}^{{{\log }_{a}}b}}=b,a>0,a\ne 1\ \text{and}\ b>0\end{array} \) which is known as the fundamental logarithmic identity. corollary 2: the function defined...
For example, let's say the base is 5. The logarithm to produce 25 would be 2, because 5 times 5 is 25. If the base is 10, the logarithm to produce 10000 would be 4. The logarithm is also called the log. Scottish mathematician John Napier coined the word by using the Greek logos...

Euler. The modern definition of logarithm was first given by the British mathematician W. Gardiner in 1742. The logarithm symbol is derived from the abbreviation of “logarithm” and is encountered in different forms almost simultaneously with the appearance of the first tables: for example, J. ...
Logarithm definition When b is raised to the power of y is equal x: by=x Then the base b logarithm of x is equal to y: logb(x)= y For example when: 24= 16 Then log2(16) = 4 Logarithm as inverse function of exponential function ...
