Lösung

vereinfachen

ln (\frac{x}{y ^{3}}) - 3 \cdot ln (\frac{1}{y}) + \frac{1}{2} \cdot ln (\frac{1}{x ^{4} y ^{2}})

ln (x (\frac{1}{x ^{4} y ^{2}})^{\frac{1}{2}})

Schritte zur Lösung

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

Wende die log Regel an:

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

3 ln (\frac{1}{y}) = ln ((\frac{1}{y})^{3})

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

Wende die log Regel an:

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

ln (\frac{x}{y ^{3}}) - ln ((\frac{1}{y})^{3}) = ln \frac{\frac{x}{y ^{3}}}{( \frac{1}{y} ) ^{3}}

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

Vereinfache

\frac{\frac{x}{y ^{3}}}{( \frac{1}{y} ) ^{3}} : x

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

Wende die log Regel an:

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

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

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

Wende die log Regel an:

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

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

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