simplify 3ln(x-8)-4ln(x)

Solution

simplify

3 ln (x - 8) - 4 ln (x)

Solution

ln (\frac{( x - 8 ) ^{3}}{x ^{4}})

Solution steps

3 ln (x - 8) - 4 ln (x)

Apply log rule:

a lo g_{c} (b) = lo g_{c} (b^{a})

3 ln (x - 8) = ln ((x - 8)^{3})

= ln ((x - 8)^{3}) - 4 ln (x)

Apply log rule:

a lo g_{c} (b) = lo g_{c} (b^{a})

4 ln (x) = ln (x^{4})

= ln ((x - 8)^{3}) - ln (x^{4})

Apply log rule:

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

ln ((x - 8)^{3}) - ln (x^{4}) = ln (\frac{( x - 8 ) ^{3}}{x ^{4}})

= ln (\frac{( x - 8 ) ^{3}}{x ^{4}})
