This free log calculator solves for the unknown portions of a logarithmic expression using base e, 2, 10, or any other desired base. On a calculator it is the "log" button. Nov 6, 2024the following free guide to the log rules shares and explains the rules of logs (including exponent log rules), what they represent, and, most importantly, how you can use them to simplify a.

The log calculator (logarithm) calculates the value of a logarithm with an arbitrary 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.

The log calculator is designed to compute the logarithm of a number to any base. It can add, subtract, multiply, and divide two log values. A negative log can be converted into a positive log using one of the following log rules:

The negative log of an argument is the logarithm of the reciprocal of the argument. I.e., -log b a = log b a -1 = log b (1/a).
