## What is the natural logarithm of 1?

What is the natural logarithm of one.

ln(1) = ?

The natural logarithm of a number x is defined as the base e logarithm of x:

ln(*x*) = log_{e}(*x*)

So

ln(1) = log_{e}(1)

Which is the number we should raise e to get 1.

*e*^{0} = 1

So the natural logarithm of one is zero:

ln(1) = log_{e}(1) = 0
