simplify ln(1/(4k))

Solution

simplify

ln (\frac{1}{4 k})

Solution

- ln (k) - 2 ln (2)

Solution steps

ln (\frac{1}{4 k})

Apply log rule:

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

ln (\frac{1}{4 k}) = ln (1) - ln (4 k)

= ln (1) - ln (4 k)

Apply log rule:

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

ln (4 k) = ln (4) + ln (k)

= ln (1) - (ln (k) + ln (4))

Apply log rule:

lo g_{a} (1) = 0

= 0 - (ln (k) + ln (4))

ln (4) = 2 ln (2)

= 0 - (ln (k) + 2 ln (2))

0 - (2 ln (2) + ln (k)) = - (2 ln (2) + ln (k))

= - (ln (k) + 2 ln (2))

Distribute parentheses

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

Apply minus-plus rules

+ (- a) = - a

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