What is ln 1?

In mathematics, ln 1 represents the natural logarithm of the number 1. The natural logarithm, denoted as ln, is the logarithm to the base e, where e is approximately 2.71828. The natural logarithm function ln(x) is the inverse of the exponential function e^x, meaning that ln(e^x) = x for all x.

Specifically, ln 1 is equal to 0 because any number raised to the power of 0 is equal to 1. Therefore, ln 1 = 0. This property of natural logarithms plays a crucial role in calculus, algebra, and various fields of science and engineering.
