Lösung

erweitern

\frac{ln ( 4 x ( x + 4 ) ^{3} )}{x + 2}

\frac{ln ( x ^{4} + 12 x ^{3} + 48 x ^{2} + 64 x )}{4 x + 8}

Schritte zur Lösung

\frac{ln ( 4 x ( x + 4 ) ^{3} )}{x + 2}

4 x (x + 4)^{3} = 4 x^{4} + 12 x^{3} + 48 x^{2} + 64 x

= \frac{ln ( 4 x ^{4} + 12 x ^{3} + 48 x ^{2} + 64 x )}{x + 2}

Vereinfache

ln (4 x^{4} + 12 x^{3} + 48 x^{2} + 64 x) : \frac{1}{4} ln (x^{4} + 12 x^{3} + 48 x^{2} + 64 x)

= \frac{\frac{1}{4} ln ( x ^{4} + 12 x ^{3} + 48 x ^{2} + 64 x )}{x + 2}

Multipliziere

\frac{1}{4} ln (x^{4} + 12 x^{3} + 48 x^{2} + 64 x) : \frac{ln ( x ^{4} + 12 x ^{3} + 48 x ^{2} + 64 x )}{4}

= \frac{\frac{l n ( x ^{4} + 12 x ^{3} + 48 x ^{2} + 64 x )}{4}}{x + 2}
