erweitern (2-14x^{12/7})/(7x^{5/7)}

Lösung

erweitern

\frac{2 - 14 x ^{\frac{12}{7}}}{7 x ^{\frac{5}{7}}}

\frac{2}{7 x ^{\frac{5}{7}}} - 2 x

Schritte zur Lösung

\frac{2 - 14 x ^{\frac{12}{7}}}{7 x ^{\frac{5}{7}}}

Wende Bruchregel an:

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

\frac{2 - 14 x ^{\frac{12}{7}}}{7 x ^{\frac{5}{7}}} = \frac{2}{7 x ^{\frac{5}{7}}} - \frac{14 x ^{\frac{12}{7}}}{7 x ^{\frac{5}{7}}}

= \frac{2}{7 x ^{\frac{5}{7}}} - \frac{14 x ^{\frac{12}{7}}}{7 x ^{\frac{5}{7}}}
