π (9 \cdot 3^{\frac{2}{3}} - 3) : 9 \cdot 3^{\frac{2}{3}} π - 3 π

= \frac{9 \cdot 3 ^{\frac{2}{3}} π - 3 π}{5}

Wende Bruchregel an:

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

\frac{9 \cdot 3 ^{\frac{2}{3}} π - 3 π}{5} = \frac{9 \cdot 3 ^{\frac{2}{3}} π}{5} - \frac{3 π}{5}

= \frac{9 \cdot 3 ^{\frac{2}{3}} π}{5} - \frac{3 π}{5}
