simplify 2ln(x+4)-7ln(x)

Solution

simplify

2 ln (x + 4) - 7 ln (x)

Solution

ln (\frac{( x + 4 ) ^{2}}{x ^{7}})

Solution steps

2 ln (x + 4) - 7 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}) - 7 ln (x)

Apply log rule:

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

7 ln (x) = ln (x^{7})

= ln ((x + 4)^{2}) - ln (x^{7})

Apply log rule:

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

ln ((x + 4)^{2}) - ln (x^{7}) = ln (\frac{( x + 4 ) ^{2}}{x ^{7}})

= ln (\frac{( x + 4 ) ^{2}}{x ^{7}})
