simplify 2ln(x+8)-9ln(x)

Solution

simplify

2 ln (x + 8) - 9 ln (x)

Solution

ln (\frac{( x + 8 ) ^{2}}{x ^{9}})

Solution steps

2 ln (x + 8) - 9 ln (x)

Apply log rule:

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

2 ln (x + 8) = ln ((x + 8)^{2})

= ln ((x + 8)^{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 + 8)^{2}) - ln (x^{9})

Apply log rule:

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

ln ((x + 8)^{2}) - ln (x^{9}) = ln (\frac{( x + 8 ) ^{2}}{x ^{9}})

= ln (\frac{( x + 8 ) ^{2}}{x ^{9}})
