Free Logarithms Calculator - Simplify logarithmic expressions using algebraic rules step-by-step.
This log calculator (logarithm calculator) allows you to calculate the logarithm of a (positive real) number with a chosen base (positive, not equal to 1). Regardless of whether you are looking for a natural logarithm, log base 2, or log base 10, this tool will solve your problem.
In its simplest form, a logarithm answers the question: How many of one number multiply together to make another number? Example: How many 2 s multiply together to make 8 ?
This free log calculator solves for the unknown portions of a logarithmic expression using base e, 2, 10, or any other desired base.

Logarithm calculator. Logarithm definition. When b is raised to the power of y is equal x: b y = x. Then the base b logarithm of x is equal to y: log b (x) = y. For example when: 2 4 = 16. Then. log 2 (16) = 4. Logarithm as inverse function of exponential function. The logarithmic function, y = log b (x)
In other words, the logarithm gives the answer to the question “How many times a number is multiplied to get the other number?”. For example, how many 3’s are multiplied to get the answer 27? If we multiply 3 for 3 times, we get the answer 27. Therefore, the logarithm is 3. The logarithm form is written as follows: Log 3 (27) = 3 ….(1)
