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, …

Sometimes a logarithm is written without a base, like this: This usually means that the base is really 10. It is called a "common logarithm". Engineers love to use it. On a calculator it is the …

Jan 5, 2026 · 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, …

For example the result for 2 x = 5 can be given as a logarithm, x = log 2 (5) . You will learn how to evaluate this logarithmic expression over the following lessons.

6 days ago · Logarithm is a mathematical function that represents the exponent to which a fixed number, known as the base, must be raised to produce a given number. In other words, it is …

What is a logarithm in easy terms? Keep in mind that whenever you are looking for the logarithm, you are looking for an exponent, or the number that tells how many times the base is …

The base b logarithm of a number is the exponent that we need to raise the base in order to get the number. The logarithm of the multiplication of x and y is the sum of logarithm of x and …

Logarithm A logarithm is the inverse function of exponentiation. A logarithm tells us the power, y, that a base, b, needs to be raised to in order to equal x. This is written as: log b (x) = y

This guide will explain what a logarithm is, how it relates to exponents, how to apply log rules, and how to use calculators to make your work quick and simple.

First, we must know the basic structure of a logarithm ((abbreviated log log for convenience)). log a b = c logab = c can be rewritten as a c = b, ac = b, where a a is called the base, c c the …
