Using logarithm is a complicated task, but this app helps out! You can choose between 4 standard shapes of this topic. Then you can enter what you have to calculate what you need - base, exponent, antilogarithm, the logarithmic result, even the x-value of a term as exponent. The connection between logarithm and exponentiation is shown aswell. An infographic gives a deeper insight into some calculation rules of the logarithm.

Decimals, fractions and negative values are supported. The solution is shown step by step. All calculations are stored in the history. The final solution can be shared.
