Introduction to Logarithms - Math is Fun
On a calculator it is the "log" button. It is how many times we need to use 10 in a multiplication, to get our desired number. Another base that is often used is e (Euler's Number) which is about 2.71828. This is called a "natural logarithm".
Logarithm - Wikipedia
In mathematics, the logarithm to base b is the inverse function of exponentiation with base b. That means that the logarithm of a number x to the base b is the exponent to which b must be raised to produce x. For example, since 1000 = 103, the logarithm base of 1000 is 3, or log10 (1000) = 3.

In this article, we are going to learn the definition of logarithms, two types of logarithms such as common logarithm and natural logarithm, and different properties of logarithms with many solved examples. John Napier introduced the concept of Logarithms in the 17th century.
Logarithm - Definition, Function, Rules, Properties & Examples
2024年12月27日 · In mathematics, a logarithm is the inverse operation of exponentiation. It is defined as the power to which the base number must be raised to get the given number. Logarithms serve as mathematical tools that help simplify complex calculations involving exponential relationships.

2024年12月21日 · 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.

2024年5月28日 · Logarithm, often called ‘logs,’ is the power to which a number must be raised to get the result. It is thus the inverse of the exponent and is written as: b a = x ⇔ log b x = a. Here, are the 3 parts of a logarithm. Thus, the logarithm represents the exponent to which a base is raised to yield a given number. For example, we know 4 3 = 64.
Logarithm (Logs) - Examples | Natural Log and Common Log - Cuemath
Here is the mathematical definition of logs. A logarithm is defined using an exponent. Here, "log" stands for logarithm. The right side part of the arrow is read to be "Logarithm of a to the base b is equal to x". A very simple way to remember this is "base stays as the base in both forms" and "base doesn't stay with the exponent in log form".

To avoid ambiguity, it is safest to use "log" to refer to base 10 logarithms and "ln" or "natural log" to refer to base e logarithms. In other words, "log (x)" typically indicates log 10 (x) and ln (x) indicates log e (x). The intent of logarithms is to help simplify calculations in areas such as science, engineering, physics, and mathematics.

The Common Logarithm log 10 (x), which is sometimes written as log(x) Engineers love to use it, but it is not used much in mathematics. On a calculator the Common Logarithm is the "log" button.

In other words, logarithm is basically what happens when we expressed a number as a power, and then take the exponent from that power — It gives us the magnitude of a number, with respect to the base in question. For example, when we try to express the number 64 as a power of 2, we get that 64 = 2 6.
