vereinfachen ln(x^2+1)+1/2 ln(x+3)-ln(x-1)

Lösung

vereinfachen

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

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

Schritte zur Lösung

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

Wende die log Regel an:

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

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

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

Wende die log Regel an:

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

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

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

Wende die log Regel an:

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

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

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