Lösung

vereinfachen

2 ln (y) + \frac{9}{5} ln (y + 2) + \frac{1}{5} ln (y - 3)

ln (y^{2} (y + 2)^{\frac{9}{5}} (y - 3)^{\frac{1}{5}})

Schritte zur Lösung

2 ln (y) + \frac{9}{5} ln (y + 2) + \frac{1}{5} ln (y - 3)

Wende die log Regel an:

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

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

= ln (y^{2}) + \frac{9}{5} ln (y + 2) + \frac{1}{5} ln (y - 3)

Wende die log Regel an:

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

\frac{9}{5} ln (y + 2) = ln ((y + 2)^{\frac{9}{5}})

= ln (y^{2}) + ln ((y + 2)^{\frac{9}{5}}) + \frac{1}{5} ln (y - 3)

Wende die log Regel an:

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

ln (y^{2}) + ln ((y + 2)^{\frac{9}{5}}) = ln (y^{2} (y + 2)^{\frac{9}{5}})

= ln (y^{2} (y + 2)^{\frac{9}{5}}) + \frac{1}{5} ln (y - 3)

Wende die log Regel an:

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

\frac{1}{5} ln (y - 3) = ln ((y - 3)^{\frac{1}{5}})

= ln (y^{2} (y + 2)^{\frac{9}{5}}) + ln ((y - 3)^{\frac{1}{5}})

Wende die log Regel an:

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

ln (y^{2} (y + 2)^{\frac{9}{5}}) + ln ((y - 3)^{\frac{1}{5}}) = ln (y^{2} (y + 2)^{\frac{9}{5}} (y - 3)^{\frac{1}{5}})

= ln (y^{2} (y + 2)^{\frac{9}{5}} (y - 3)^{\frac{1}{5}})
