To compute the logarithm with an arbitrary base just enter your number and base in the corresponding calculator fields:

The calculator uses the following formula to get the algorithm with arbitrary base:

In addition the calculator gives a base-10 logarithm (common logarithm) and natural logarithm of the given number.
