ln (\frac{8 x ^{5} x + 3}{x + 3})

Schritte zur Lösung

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

Wende die log Regel an:

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

3 ln (2) = ln (2^{3})

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

Wende die log Regel an:

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

5 ln (x) = ln (x^{5})

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

Wende die log Regel an:

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

ln (2^{3}) + ln (x^{5}) = ln (2^{3} x^{5})

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

2^{3} = 8

= ln (8 x^{5}) - \frac{1}{2} ln (x + 3)

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 (8 x^{5}) - ln ((x + 3)^{\frac{1}{2}})

Wende die log Regel an:

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

ln (8 x^{5}) - ln ((x + 3)^{\frac{1}{2}}) = ln (\frac{8 x ^{5}}{( x + 3 ) ^{\frac{1}{2}}})

= ln (\frac{8 x ^{5}}{( x + 3 ) ^{\frac{1}{2}}})

Vereinfache

\frac{8 x ^{5}}{( x + 3 ) ^{\frac{1}{2}}} : \frac{8 x ^{5} x + 3}{x + 3}

= ln (\frac{8 x ^{5} x + 3}{x + 3})
