Identify Properties: Identify the properties of logarithms that can be applied to the problem.The natural logarithm of 1 over e, ln(e1), can be rewritten using the property of logarithms that states ln(ba)=ln(a)−ln(b).
Apply Property: Apply the logarithm property to the given expression. ln(e1)=ln(1)−ln(e)
Simplify Logarithms: Simplify the natural logarithm of 1 and the natural logarithm of e.ln(1) is always 0 because e0=1, and ln(e) is always 1 because e1=e. So, ln(1)−ln(e)=0−1
Calculate Final Value: Calculate the final simplified value.0−1=−1
