Lösung

vereinfachen

2 ln (x - 1) + 3 ln (4) - ln (x)

ln (\frac{64 ( x - 1 ) ^{2}}{x})

Schritte zur Lösung

2 ln (x - 1) + 3 ln (4) - ln (x)

Wende die log Regel an:

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

2 ln (x - 1) = ln ((x - 1)^{2})

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

Wende die log Regel an:

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

3 ln (4) = ln (4^{3})

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

Wende die log Regel an:

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

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

= ln (4^{3} (x - 1)^{2}) - ln (x)

4^{3} = 64

= ln (64 (x - 1)^{2}) - ln (x)

Wende die log Regel an:

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

ln (64 (x - 1)^{2}) - ln (x) = ln (\frac{64 ( x - 1 ) ^{2}}{x})

= ln (\frac{64 ( x - 1 ) ^{2}}{x})
