simplify ln((x^2)/((x+1)^3))

Solution

simplify

ln (\frac{x ^{2}}{( x + 1 ) ^{3}})

Solution

2 ln (x) - 3 ln (x + 1)

Solution steps

ln (\frac{x ^{2}}{( x + 1 ) ^{3}})

Apply log rule:

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

ln (\frac{x ^{2}}{( x + 1 ) ^{3}}) = ln (x^{2}) - ln ((x + 1)^{3})

= ln (x^{2}) - ln ((x + 1)^{3})

Apply log rule:

lo g_{a} (x^{b}) = b \cdot lo g_{a} (x)

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

= 2 ln (x) - ln ((x + 1)^{3})

Apply log rule:

lo g_{a} (x^{b}) = b \cdot lo g_{a} (x)

ln ((x + 1)^{3}) = 3 ln (x + 1)

= 2 ln (x) - 3 ln (x + 1)
