Evaluate Using the Given Value natural log of 81 , natural log of 3=p

$\ln (81)$ , $\ln (3) = p$

Subtract $\ln (3)$ from both sides of the equation.

$0 = p - \ln (3)$

Rewrite the equation as $p - \ln (3) = 0$ .

$p - \ln (3) = 0$

Replace the variable $p - \ln (3)$ with $0$ in the expression.

$\ln (81)$

The result can be shown in multiple forms.

Exact Form:

$\ln (81)$

Decimal Form:

$4.39444915 \dots$
