On a calculator it is the "log" button.

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 …

Aug 13, 2025 · 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 …

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.

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 multiplied. For …

There are three main types of logarithms in Mathematics, namely the common logarithm, the natural logarithm, and the binary logarithm. Let’s discuss each in detail.

What Is a Logarithm in Math? A logarithm is the opposite of an exponent. When you see something like $$2^ {3} = 8$$, the logarithmic form asks: “To what power must 2 be raised to get 8?” The answer is …

Logarithms are another way of thinking about exponents. For example, we know that 2 raised to the 4 th power equals 16 . This is expressed by the exponential equation 2 4 = 16 . Now, suppose someone …

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

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 …
