vereinfachen 1/2 [ln(x)+2ln(x+1)]+3ln(x-5)

Lösung

vereinfachen

\frac{1}{2} [ln (x) + 2 ln (x + 1)] + 3 ln (x - 5)

\frac{1}{2} ln (x (x + 1)^{2}) + 3 ln (x - 5)

Schritte zur Lösung

\frac{1}{2} [ln (x) + 2 ln (x + 1)] + 3 ln (x - 5)

Wende die log Regel an:

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

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

= \frac{1}{2} [ln (x) + ln ((x + 1)^{2})] + 3 ln (x - 5)

Wende die log Regel an:

lo g_{c} (a) + lo g_{c} (b) = lo g_{c} (ab)

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

= \frac{1}{2} [ln (x (x + 1)^{2})] + 3 ln (x - 5)
