Lösung

erweitern

1 + (\frac{( 4 x ^{4} - 1 ) ^{2}}{16 x ^{4}})

1 + x^{4} - \frac{1}{2} + \frac{1}{16 x ^{4}}

Schritte zur Lösung

1 + (\frac{( 4 x ^{4} - 1 ) ^{2}}{16 x ^{4}})

Entferne die Klammern:

(a) = a

= 1 + \frac{( 4 x ^{4} - 1 ) ^{2}}{16 x ^{4}}

(4 x^{4} - 1)^{2} = 16 x^{8} - 8 x^{4} + 1

= 1 + \frac{16 x ^{8} - 8 x ^{4} + 1}{16 x ^{4}}

Wende Bruchregel an:

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

\frac{16 x ^{8} - 8 x ^{4} + 1}{16 x ^{4}} = \frac{16 x ^{8}}{16 x ^{4}} - \frac{8 x ^{4}}{16 x ^{4}} + \frac{1}{16 x ^{4}}

= 1 + \frac{16 x ^{8}}{16 x ^{4}} - \frac{8 x ^{4}}{16 x ^{4}} + \frac{1}{16 x ^{4}}
