Evaluate ln 1
To evaluate ln 1, use the basic properties of logarithms . First recall that by the definition of the natural logarithm , ln x = log ex.
Note that the given express is the form log b1.
The basic property of logarithms states that for b > 0, b ≠ 1, log b1 =0.
Apply the property to the given expression.
ln 1 = 0
Therefore, ln 1 = 0.
