Question

How do you simplify `In e`?

Answer 1

`lne=1`

Explanation:

`ln` stands for natural logarithm i.e. to the base `e` a real number known as Euler's number or Napier's constant, which can be written as `e=Sigma_(n=0)^(n=oo)1/(n!)`

In fact Napier used this to define what is known as natural log i.e. to the base `e`. In this if a number `a=e^x` then `x=lna`.

Hence, as `e=e^1`, we have

`lne=1`
