vereinfachen 3(ln(3)-ln(x^2))+(ln(x)-ln(9))

Lösung

vereinfachen

3 (ln (3) - ln (x^{2})) + (ln (x) - ln (9))

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

Schritte zur Lösung

3 (ln (3) - ln (x^{2})) + (ln (x) - ln (9))

Wende die log Regel an:

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

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

= 3 ln (\frac{3}{x ^{2}}) + + ln (x) - ln (9)

Wende die log Regel an:

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

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

= ln ((\frac{3}{x ^{2}})^{3}) + + ln (x) - ln (9)

Wende die log Regel an:

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

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

= ln ((\frac{3}{x ^{2}})^{3} x) - ln (9)

Vereinfache

(\frac{3}{x ^{2}})^{3} x : \frac{27}{x ^{5}}

= ln (\frac{27}{x ^{5}}) - ln (9)

Wende die log Regel an:

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

ln (\frac{27}{x ^{5}}) - ln (9) = ln (\frac{\frac{27}{x ^{5}}}{9})

= ln (\frac{\frac{27}{x ^{5}}}{9})

Vereinfache

\frac{\frac{27}{x ^{5}}}{9} : \frac{3}{x ^{5}}

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