simplify ln^2(-1)+2ln(-1)

Solution

simplify

ln^{2} (- 1) + 2 ln (- 1)

Solution

ln^{2} (- 1)

Solution steps

ln^{2} (- 1) + 2 ln (- 1)

Apply log rule:

a lo g_{c} (b) = lo g_{c} (b^{a})

2 ln (- 1) = ln ((- 1)^{2})

= ln^{2} (- 1) + ln ((- 1)^{2})

Apply log rule:

lo g_{c} (a) + lo g_{c} (b) = lo g_{c} (ab)

ln^{2} (- 1) + ln ((- 1)^{2}) = ln^{2} (- (- 1)^{2} \cdot 1)

= ln^{2} (- (- 1)^{2} \cdot 1)

- 1 \cdot (- 1)^{2} = - 1

= ln^{2} (- 1)
