ln (\frac{4 \cdot 2 ^{\frac{3}{5}} x ^{12}}{y ^{8}})

Schritte zur Lösung

\frac{3}{2} ln (4 x^{8}) - \frac{2}{5} ln (2 y^{20})

Wende die log Regel an:

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

\frac{3}{2} ln (4 x^{8}) = ln ((4 x^{8})^{\frac{3}{2}})

= ln ((4 x^{8})^{\frac{3}{2}}) - \frac{2}{5} ln (2 y^{20})

Wende die log Regel an:

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

\frac{2}{5} ln (2 y^{20}) = ln ((2 y^{20})^{\frac{2}{5}})

= ln ((4 x^{8})^{\frac{3}{2}}) - ln ((2 y^{20})^{\frac{2}{5}})

Wende die log Regel an:

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

ln ((4 x^{8})^{\frac{3}{2}}) - ln ((2 y^{20})^{\frac{2}{5}}) = ln \frac{( 4 x ^{8} ) ^{\frac{3}{2}}}{( 2 y ^{20} ) ^{\frac{2}{5}}}

= ln \frac{( 4 x ^{8} ) ^{\frac{3}{2}}}{( 2 y ^{20} ) ^{\frac{2}{5}}}

Vereinfache

\frac{( 4 x ^{8} ) ^{\frac{3}{2}}}{( 2 y ^{20} ) ^{\frac{2}{5}}} : \frac{2 ^{2} \cdot 2 ^{\frac{3}{5}} x ^{12}}{y ^{8}}

= ln (\frac{2 ^{2} \cdot 2 ^{\frac{3}{5}} x ^{12}}{y ^{8}})

\frac{2 ^{2} \cdot 2 ^{\frac{3}{5}} x ^{12}}{y ^{8}} = \frac{2 ^{2 + \frac{3}{5}} x ^{12}}{y ^{8}}

= ln (\frac{2 ^{2 + \frac{3}{5}} x ^{12}}{y ^{8}})

\frac{2 ^{2 + \frac{3}{5}} x ^{12}}{y ^{8}} = \frac{4 \cdot 2 ^{\frac{3}{5}} x ^{12}}{y ^{8}}

= ln (\frac{4 \cdot 2 ^{\frac{3}{5}} x ^{12}}{y ^{8}})
