Solution

simplify

ln (\frac{1}{81})

Solution

- 4 ln (3)

+1

Decimal Notation

- 4.39444 \dots

Solution steps

ln (\frac{1}{81})

Apply log rule:

lo g_{c} (\frac{a}{b}) = lo g_{c} (a) - lo g_{c} (b)

ln (\frac{1}{81}) = ln (1) - ln (81)

= ln (1) - ln (81)

Apply log rule:

lo g_{a} (1) = 0

= 0 - ln (81)

0 - ln (81) = - ln (81)

= - ln (81)

Simplify

ln (81) : 4 ln (3)

= - 4 ln (3)
