vereinfachen ln(6+x^2)+2ln(x)-ln(x+1)

Lösung

vereinfachen

ln (6 + x^{2}) + 2 ln (x) - ln (x + 1)

ln (\frac{( 6 + x ^{2} ) x ^{2}}{x + 1})

Schritte zur Lösung

ln (6 + x^{2}) + 2 ln (x) - ln (x + 1)

Wende die log Regel an:

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

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

= ln (x^{2} + 6) + ln (x^{2}) - ln (x + 1)

Wende die log Regel an:

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

ln (6 + x^{2}) + ln (x^{2}) = ln (x^{2} (x^{2} + 6))

= ln ((6 + x^{2}) x^{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} (6 + x^{2})) - ln (x + 1) = ln (\frac{x ^{2} ( x ^{2} + 6 )}{x + 1})

= ln (\frac{( 6 + x ^{2} ) x ^{2}}{x + 1})
