How I could show that :log1=0? I would be like somone to show me or give me a prove for this : Why ln1=0 ? Note that ln is logarithme népérien, the natural logarithm of a number is its logarithm to the base e. Thanks for any replies or any comments!

log 1 = log ( 1 1 ) = log 1 + log 1 So  log 1 = log 1 + log 1 log 1 = log 1 0 = log 1

I will denote the natural logarithm of x by ln x
There are several definitions of the natural logarithm, so I will look at two of them.
1) ln ( ) : ( 0 , ) R is the inverse of the exponential function e : R ( 0 , ), where ( 0 , ) denotes the set of positive real numbers. Then because a 0 = 1 for every real number a, particularly e, it follows that ln ( 1 ) = 0
2) ln x = 1 x d t t . Then Evaluating at 1 gives ln 1 = 1 1 d x x = 0
