What is the natural logarithm of e?

What the natural logarithm of the e constant (Euler's constant)?

ln(e) = ?

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

ln(x) = log_e(x)

So the natural logarithm of e is the base e logarithm of e:

ln(e) = log_e(e)

ln(e) is the number we should raise e to get e.

e¹ = e

So the natural logarithm of e is equal to one.

ln(e) = log_e(e) = 1
