Free Logarithms Calculator - Simplify logarithmic expressions using algebraic rules step-by-step
Rewrite log5 (125) = x log 5 (125) = x in exponential form using the definition of a logarithm. If x x and b b are positive real numbers and b b does not equal 1 1, then logb (x) = y log b (x) = y is equivalent to by = x b y = x. Create equivalent expressions in the equation that all have equal bases.

This free log calculator solves for the unknown portions of a logarithmic expression using base e, 2, 10, or any other desired base.
When using our logarithm calculator you need to enter a "Base" of 10 for the common logarithm, 2 for the binary logarithm, and leave the "Base" field empty to get the natural logarithm calculated.
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.
\displaystyle{{\log}_{{5}}{125}}={3} can be rewritten as \displaystyle{5}^{{3}}={125} . Explanation: When converting a logarithm to an exponential equation, the first thing you can do is ... How do you evaluate \displaystyle{{\log}_{{125}}{5}} ?
