Lösung

erweitern

\frac{( - \frac{6}{5} x ^{3} y ^{2} )}{( \frac{3}{5} x ^{2} y ^{2} )}

- 2 x

Schritte zur Lösung

\frac{- \frac{6}{5} x ^{3} y ^{2}}{\frac{3}{5} x ^{2} y ^{2}}

Wende Bruchregel an:

\frac{- a}{b} = - \frac{a}{b}

= - \frac{\frac{6}{5} x ^{3} y ^{2}}{\frac{3}{5} x ^{2} y ^{2}}

Multipliziere

\frac{6}{5} x^{3} y^{2} : \frac{6 x ^{3} y ^{2}}{5}

= - \frac{\frac{6 x ^{3} y ^{2}}{5}}{\frac{3}{5} x ^{2} y ^{2}}

Wende Bruchregel an:

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

= - \frac{6 x ^{3} y ^{2}}{5 \cdot \frac{3}{5} x ^{2} y ^{2}}

Multipliziere

5 \cdot \frac{3}{5} x^{2} y^{2} : 3 x^{2} y^{2}

= - \frac{6 x ^{3} y ^{2}}{3 x ^{2} y ^{2}}

Teile die Zahlen:

\frac{6}{3} = 2

= \frac{2 x ^{3} y ^{2}}{x ^{2} y ^{2}}

Wende Exponentenregel an:

\frac{x ^{a}}{x ^{b}} = x^{a - b}

\frac{x ^{3}}{x ^{2}} = x^{3 - 2}

= \frac{2 y ^{2} x ^{3 - 2}}{y ^{2}}
