Lösung

vereinfachen

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

ln (\frac{x ^{5}}{y ^{2} ( x + y ) ^{2}})

Schritte zur Lösung

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

Wende die log Regel an:

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

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

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

Wende die log Regel an:

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

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

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

Vereinfache

x^{2} \frac{x ^{3}}{y ^{2}} : \frac{x ^{5}}{y ^{2}}

= ln (\frac{x ^{5}}{y ^{2}}) - 4 ln (x + y)

Wende die log Regel an:

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

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

= ln (\frac{x ^{5}}{y ^{2}}) - ln ((x + y)^{4})

Wende die log Regel an:

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

ln (\frac{x ^{5}}{y ^{2}}) - ln ((x + y)^{4}) = ln (\frac{\frac{x ^{5}}{y ^{2}}}{( x + y ) ^{4}})

= ln (\frac{\frac{x ^{5}}{y ^{2}}}{( x + y ) ^{4}})

Vereinfache

\frac{\frac{x ^{5}}{y ^{2}}}{( x + y ) ^{4}} : \frac{x ^{5}}{y ^{2} ( x + y ) ^{2}}

= ln (\frac{x ^{5}}{y ^{2} ( x + y ) ^{2}})
