simplify [ln(-1)-ln(-2)]

Solution

simplify

[ln (- 1) - ln (- 2)]

Solution

- ln (2)

+1

Decimal Notation

- 0.69314 \dots

Solution steps

[ln (- 1) - ln (- 2)]

Apply log rule:

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

ln (- 1) - ln (- 2) = ln (\frac{- 1}{- 2})

= [ln (\frac{- 1}{- 2})]

Apply the fraction rule:

\frac{- a}{- b} = \frac{a}{b}

= [ln (\frac{1}{2})]

Remove parentheses:

(a) = a

= ln (\frac{1}{2})

Apply log rule:

lo g_{a} (\frac{1}{x}) = - lo g_{a} (x)

= - ln (2)
