erweitern \sqrt[4]{(x-1)}(x+1)(x^2+1)(x^4+1)+1

Lösung

erweitern

4 (x - 1) (x + 1) (x^{2} + 1) (x^{4} + 1) + 1

x^{7} 4 x - 1 + x^{5} 4 x - 1 + x^{6} 4 x - 1 + x^{4} 4 x - 1 + x^{3} 4 x - 1 + x 4 x - 1 + x^{2} 4 x - 1 + 4 x - 1 + 1

Schritte zur Lösung

4 x - 1 (x + 1) (x^{2} + 1) (x^{4} + 1) + 1

Vereinfache

(x - 1) : x - 1

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

Schreibe

4 x - 1 (x + 1) (x^{2} + 1) (x^{4} + 1)

um:
