simplify 7ln(x+2)-5ln(x)

Solution

simplify

7 ln (x + 2) - 5 ln (x)

Solution

ln (\frac{( x + 2 ) ^{7}}{x ^{5}})

Solution steps

7 ln (x + 2) - 5 ln (x)

Apply log rule:

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

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

= ln ((x + 2)^{7}) - 5 ln (x)

Apply log rule:

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

5 ln (x) = ln (x^{5})

= ln ((x + 2)^{7}) - ln (x^{5})

Apply log rule:

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

ln ((x + 2)^{7}) - ln (x^{5}) = ln (\frac{( x + 2 ) ^{7}}{x ^{5}})

= ln (\frac{( x + 2 ) ^{7}}{x ^{5}})
