simplify 2ln(-2)-2ln(2)

Solution

simplify

2 \cdot ln (- 2) - 2 \cdot ln (2)

Solution

0

Solution steps

2 ln (- 2) - 2 ln (2)

Apply log rule:

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

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

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

Apply log rule:

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

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

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

Apply log rule:

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

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

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

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

= ln (1)

Apply log rule:

lo g_{a} (1) = 0

= 0
