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

Solution

simplify

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

Solution

4 ln (2)

+1

Decimal Notation

2.77258 \dots

Solution steps

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

Apply log rule:

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

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

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

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

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

Apply rule

- (- a) = a

= 2 ln (2) + 2 ln (2)

Add similar elements:

2 ln (2) + 2 ln (2) = 4 ln (2)

= 4 ln (2)
