Identify Components: Identify the components of the expression ln(e41). In ln(e41), we have a natural logarithm of a fraction where the denominator is e raised to the power of 4.
Apply Power Rule: Apply the logarithm power rule.The power rule of logarithms states that ln(ab)=b⋅ln(a). We can apply this rule in reverse since the denominator is e raised to the power of 4.ln(e41)=ln(1)−ln(e4)
Simplify Logarithms: Simplify the logarithms.We know that ln(1)=0 because e0=1. Also, ln(e4)=4 because the base of the natural logarithm is e.ln(e41)=0−4
Perform Subtraction: Perform the subtraction.0−4=−4
