Lösung

vereinfachen

\frac{1}{4} [3 ln (x + 4) - ln (x) - ln (x^{2} - 9)]

\frac{1}{4} ln (\frac{( x + 4 ) ^{3}}{x ( x ^{2} - 9 )})

Schritte zur Lösung

\frac{1}{4} [3 ln (x + 4) - ln (x) - ln (x^{2} - 9)]

Wende die log Regel an:

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

3 ln (x + 4) = ln ((x + 4)^{3})

= \frac{1}{4} [ln ((x + 4)^{3}) - ln (x) - ln (x^{2} - 9)]

Wende die log Regel an:

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

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

= \frac{1}{4} [ln (\frac{( x + 4 ) ^{3}}{x}) - ln (x^{2} - 9)]

Wende die log Regel an:

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

ln (\frac{( x + 4 ) ^{3}}{x}) - ln (x^{2} - 9) = ln (\frac{\frac{( x + 4 ) ^{3}}{x}}{x ^{2} - 9})

= \frac{1}{4} [ln (\frac{\frac{( x + 4 ) ^{3}}{x}}{x ^{2} - 9})]

Wende Bruchregel an:

\frac{\frac{b}{c}}{a} = \frac{b}{c \cdot a}

= \frac{1}{4} [ln (\frac{( x + 4 ) ^{3}}{x ( x ^{2} - 9 )})]
