vereinfachen 5ln(a)+2ln(b)-7ln(c)+3ln(2)

Lösung

vereinfachen

5 ln (a) + 2 ln (b) - 7 ln (c) + 3 ln (2)

ln (\frac{8 a ^{5} b ^{2}}{c ^{7}})

Schritte zur Lösung

5 ln (a) + 2 ln (b) - 7 ln (c) + 3 ln (2)

Wende die log Regel an:

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

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

= ln (a^{5}) + 2 ln (b) - 7 ln (c) + 3 ln (2)

Wende die log Regel an:

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

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

= ln (a^{5}) + ln (b^{2}) - 7 ln (c) + 3 ln (2)

Wende die log Regel an:

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

ln (a^{5}) + ln (b^{2}) = ln (a^{5} b^{2})

= ln (a^{5} b^{2}) - 7 ln (c) + 3 ln (2)

Wende die log Regel an:

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

7 ln (c) = ln (c^{7})

= ln (a^{5} b^{2}) - ln (c^{7}) + 3 ln (2)

Wende die log Regel an:

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

ln (a^{5} b^{2}) - ln (c^{7}) = ln (\frac{a ^{5} b ^{2}}{c ^{7}})

= ln (\frac{a ^{5} b ^{2}}{c ^{7}}) + 3 ln (2)

Wende die log Regel an:

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

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

= ln (\frac{a ^{5} b ^{2}}{c ^{7}}) + ln (2^{3})

Wende die log Regel an:

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

ln (\frac{a ^{5} b ^{2}}{c ^{7}}) + ln (2^{3}) = ln (2^{3} \cdot \frac{a ^{5} b ^{2}}{c ^{7}})

= ln (2^{3} \cdot \frac{a ^{5} b ^{2}}{c ^{7}})

Vereinfache

\frac{a ^{5} b ^{2}}{c ^{7}} \cdot 2^{3} : \frac{8 a ^{5} b ^{2}}{c ^{7}}

= ln (\frac{8 a ^{5} b ^{2}}{c ^{7}})
