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

Solution

simplify

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

Solution

ln (2) - ln (3)

+1

Decimal Notation

- 0.40546 \dots

Solution steps

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

Apply log rule:

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

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

= ln (1 - (- 1)) - ln (1 + 2)

Apply rule

- (- a) = a

= ln (1 + 1) - ln (1 + 2)

Add the numbers:

1 + 1 = 2

= ln (2) - ln (1 + 2)

Add the numbers:

1 + 2 = 3

= ln (2) - ln (3)
