simplify 2ln(x-4)-9ln(x)

Solution

simplify

2 ln (x - 4) - 9 ln (x)

Solution

ln (\frac{( x - 4 ) ^{2}}{x ^{9}})

Solution steps

2 ln (x - 4) - 9 ln (x)

Apply log rule:

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

2 ln (x - 4) = ln ((x - 4)^{2})

= ln ((x - 4)^{2}) - 9 ln (x)

Apply log rule:

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

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

= ln ((x - 4)^{2}) - ln (x^{9})

Apply log rule:

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

ln ((x - 4)^{2}) - ln (x^{9}) = ln (\frac{( x - 4 ) ^{2}}{x ^{9}})

= ln (\frac{( x - 4 ) ^{2}}{x ^{9}})
