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, …

On a calculator it is the "log" button.

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.

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 …

To calculate the logarithm of a number x with base b, enter your values below. Did we solve your problem today? The log calculator (logarithm) calculates the value of a logarithm with an …

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 …

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 …

In the Wolfram Language, the logarithm to the base is implemented as Log [b, x], while Log [x] gives the natural logarithm, i.e., Log [E, x], where E is the Wolfram Language symbol for e.

This free log calculator solves for the unknown portions of a logarithmic expression using base e, 2, 10, or any other desired base.

Learn the eight (8) log rules or laws to help you evaluate, expand, condense, and solve logarithmic equations. Try out the log rules practice problems for an even better understanding.
