Lösung

vereinfachen

4 ln (2) + 2 ln (x) - 12 ln (x + 3)

ln (\frac{16 x ^{2}}{( x + 3 ) ^{12}})

Schritte zur Lösung

4 ln (2) + 2 ln (x) - 12 ln (x + 3)

Wende die log Regel an:

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

4 ln (2) = ln (2^{4})

= ln (2^{4}) + 2 ln (x) - 12 ln (x + 3)

Wende die log Regel an:

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

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

= ln (2^{4}) + ln (x^{2}) - 12 ln (x + 3)

Wende die log Regel an:

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

ln (2^{4}) + ln (x^{2}) = ln (2^{4} x^{2})

= ln (2^{4} x^{2}) - 12 ln (x + 3)

2^{4} = 16

= ln (16 x^{2}) - 12 ln (x + 3)

Wende die log Regel an:

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

12 ln (x + 3) = ln ((x + 3)^{12})

= ln (16 x^{2}) - ln ((x + 3)^{12})

Wende die log Regel an:

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

ln (16 x^{2}) - ln ((x + 3)^{12}) = ln (\frac{16 x ^{2}}{( x + 3 ) ^{12}})

= ln (\frac{16 x ^{2}}{( x + 3 ) ^{12}})
