simplify 9ln(x+4)-3ln(x)

Solution

simplify

9 ln (x + 4) - 3 ln (x)

Solution

ln (\frac{( x + 4 ) ^{9}}{x ^{3}})

Solution steps

9 ln (x + 4) - 3 ln (x)

Apply log rule:

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

9 ln (x + 4) = ln ((x + 4)^{9})

= ln ((x + 4)^{9}) - 3 ln (x)

Apply log rule:

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

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

= ln ((x + 4)^{9}) - ln (x^{3})

Apply log rule:

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

ln ((x + 4)^{9}) - ln (x^{3}) = ln (\frac{( x + 4 ) ^{9}}{x ^{3}})

= ln (\frac{( x + 4 ) ^{9}}{x ^{3}})
