simplify ln(a)-ln(d)-ln(c)

simplify

ln (a) - ln (d) - ln (c)

ln (\frac{a}{d c})

Solution steps

ln (a) - ln (d) - ln (c)

Apply log rule:

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

ln (a) - ln (d) = ln (\frac{a}{d})

= ln (\frac{a}{d}) - ln (c)

Apply log rule:

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

ln (\frac{a}{d}) - ln (c) = ln (\frac{\frac{a}{d}}{c})

= ln (\frac{\frac{a}{d}}{c})

Apply the fraction rule:

\frac{\frac{b}{c}}{a} = \frac{b}{c \cdot a}

= ln (\frac{a}{d c})

lo g_{10} (100 x)

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

lo g_{10} (a) + lo g_{10} (b)

lo g_{10} (5 x)

lo g_{10} (3 x)
