Frequently Asked Questions
What is a Logarithm?
A logarithm is the inverse function of exponentiation: log_b(x) = y means that base b raised to the power y equals x (b^y = x).
What is the difference between ln and log10?
Natural log ln(x) uses the mathematical constant e ≈ 2.71828 as its base, while common log log10(x) uses base 10.
