12 (2 - e^{\frac{π}{12}}) : 122 - 12 e^{\frac{π}{12}}

= \frac{12 2 - 12 e ^{\frac{π}{12}}}{π e ^{\frac{π}{4}}}

Wende Bruchregel an:

\frac{a \pm b}{c} = \frac{a}{c} \pm \frac{b}{c}

\frac{12 2 - 12 e ^{\frac{π}{12}}}{π e ^{\frac{π}{4}}} = \frac{12 2}{π e ^{\frac{π}{4}}} - \frac{12 e ^{\frac{π}{12}}}{π e ^{\frac{π}{4}}}

= \frac{12 2}{π e ^{\frac{π}{4}}} - \frac{12 e ^{\frac{π}{12}}}{π e ^{\frac{π}{4}}}
