vereinfachen 3/4 ln(x)+ln(sqrt(x^2+1))-7ln(4x+5)

Lösung

vereinfachen

\frac{3}{4} ln (x) + ln (x^{2} + 1) - 7 ln (4 x + 5)

ln (\frac{x ^{\frac{3}{4}} x ^{2} + 1}{( 4 x + 5 ) ^{7}})

Schritte zur Lösung

\frac{3}{4} ln (x) + ln (x^{2} + 1) - 7 ln (4 x + 5)

Wende die log Regel an:

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

\frac{3}{4} ln (x) = ln (x^{\frac{3}{4}})

= ln (x^{\frac{3}{4}}) + ln (x^{2} + 1) - 7 ln (4 x + 5)

Wende die log Regel an:

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

ln (x^{\frac{3}{4}}) + ln (x^{2} + 1) = ln (x^{\frac{3}{4}} x^{2} + 1)

= ln (x^{\frac{3}{4}} x^{2} + 1) - 7 ln (4 x + 5)

Wende die log Regel an:

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

7 ln (4 x + 5) = ln ((4 x + 5)^{7})

= ln (x^{\frac{3}{4}} x^{2} + 1) - ln ((4 x + 5)^{7})

Wende die log Regel an:

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

ln (x^{\frac{3}{4}} x^{2} + 1) - ln ((4 x + 5)^{7}) = ln (\frac{x ^{\frac{3}{4}} x ^{2} + 1}{( 4 x + 5 ) ^{7}})

= ln (\frac{x ^{\frac{3}{4}} x ^{2} + 1}{( 4 x + 5 ) ^{7}})
