This free log calculator solves for the unknown portions of a logarithmic expression using base e, 2, 10, or any other desired base.

All terms on top of the fraction inside the logarithm are positive and the log (y 5) is subtracted since it has been divided inside the logarithm. We can then use the power law of logarithms to bring down …

In its simplest form, a logarithm answers the question: How many of one number multiply together to make another number?

May 10, 2026 · Expressed mathematically, x is the logarithm of n to the base b if bx = n, in which case one writes x = log b n. For example, 2 3 = 8; therefore, 3 is the logarithm of 8 to base 2, or 3 = log 2 8.
