Solution steps

ln (\frac{1}{18})

Apply log rule:

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

ln (\frac{1}{18}) = ln (1) - ln (18)

= ln (1) - ln (18)

Apply log rule:

lo g_{a} (1) = 0

= 0 - ln (18)

0 - ln (18) = - ln (18)

= - ln (18)

ln (x) - (ln (y) + ln (z)) - 2 ln (a)

lo g_{8} (3 x^{4})

lo g_{8} (x^{3})

ln (\frac{4.7926}{- 4.92})

lo g_{7} ((a^{4} b)^{4})
