Lösung

erweitern

(\frac{( 2 x + 8 )}{6})^{3}

\frac{x ^{3}}{27} + \frac{4 x ^{2}}{9} + \frac{16 x}{9} + \frac{64}{27}

Schritte zur Lösung

(\frac{2 x + 8}{6})^{3}

\frac{2 x + 8}{6} = \frac{x + 4}{3}

= (\frac{x + 4}{3})^{3}

Wende Exponentenregel an:

(\frac{a}{b})^{c} = \frac{a ^{c}}{b ^{c}}

= \frac{( x + 4 ) ^{3}}{3 ^{3}}

(x + 4)^{3} = x^{3} + 12 x^{2} + 48 x + 64

= \frac{x ^{3} + 12 x ^{2} + 48 x + 64}{3 ^{3}}

3^{3} = 27

= \frac{x ^{3} + 12 x ^{2} + 48 x + 64}{27}

Wende Bruchregel an:

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

\frac{x ^{3} + 12 x ^{2} + 48 x + 64}{27} = \frac{x ^{3}}{27} + \frac{12 x ^{2}}{27} + \frac{48 x}{27} + \frac{64}{27}

= \frac{x ^{3}}{27} + \frac{12 x ^{2}}{27} + \frac{48 x}{27} + \frac{64}{27}

Streiche

= \frac{x ^{3}}{27} + \frac{4 x ^{2}}{9} + \frac{48 x}{27} + \frac{64}{27}

Streiche

\frac{48 x}{27} : \frac{16 x}{9}

= \frac{x ^{3}}{27} + \frac{4 x ^{2}}{9} + \frac{16 x}{9} + \frac{64}{27}
