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 …

Exponents and Logarithms are related, let's discover how ... The exponent says how many times to use the number in a multiplication. In this example: 23 = 2 × 2 × 2 = 8. So an exponent gives you this …

Feb 16, 2026 · In general, finer intervals are required for calculating logarithmic functions of smaller numbers—for example, in the calculation of the functions log sin x and log tan x.

Learn about the properties of logarithms that help us rewrite logarithmic expressions, and about the change of base rule that allows us to evaluate any logarithm we want using the calculator.

Jan 13, 2026 · 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 the …

May 28, 2024 · What is a logarithm and how it works with examples. How to solve logarithmic equations is explained with the formula. Also, learn natural and common logarithms.

Two of the most commonly used bases are base 10 (common logarithm) and base e (natural logarithm). Generally, when someone says (or writes) "log" without specifying the base, the convention is to …

To understand logarithms, it is sufficient to know that a logarithmic equation is just another way of writing an exponential equation. Logarithm and exponent are inverse forms of each other.

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 of y. …

Specifically, a logarithm is the power to which a number (the base) must be raised to produce a given number. For example, \ (\log_2 64 = 6,\) because \ ( 2^6 = 64.\) In general, we have the following …
