Identify Logarithm Properties: Identify the properties of logarithms that can be applied to the problem.The natural logarithm of the reciprocal of e can be simplified using the property ln(x1)=−ln(x).
Apply Logarithm Property: Apply the logarithm property to the given problem.ln(e1)=−ln(e)
Simplify Natural Logarithm: Simplify the natural logarithm of e.Since ln(e) is equal to 1, we have −ln(e)=−1.
Conclude Solution: Conclude the solution.The value of ln(e1) is −1.
