Solution

simplify

4 ln (\frac{2}{8})

Solution

- 8 ln (2)

+1

Decimal Notation

- 5.54517 \dots

Solution steps

4 ln (\frac{2}{8})

Apply log rule:

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

ln (\frac{2}{8}) = ln (2) - ln (8)

= 4 (ln (2) - ln (8))

ln (8) = 3 ln (2)

= 4 (ln (2) - 3 ln (2))

Add similar elements:

ln (2) - 3 ln (2) = - 2 ln (2)

= 4 (- 2 ln (2))

Remove parentheses:

(- a) = - a

= - 4 \cdot 2 ln (2)

Multiply the numbers:

4 \cdot 2 = 8

= - 8 ln (2)
