R e (x + y)^{4}

e R x^{4} + 4 e R x^{3} y + 6 e R x^{2} y^{2} + 4 e R x y^{3} + e R y^{4}

Schritte zur Lösung

R e (x + y)^{4}

(x + y)^{4} = x^{4} + 4 x^{3} y + 6 x^{2} y^{2} + 4 x y^{3} + y^{4}

= e R (x^{4} + 4 x^{3} y + 6 x^{2} y^{2} + 4 x y^{3} + y^{4})

= e R (x^{4} + 4 x^{3} y + 6 x^{2} y^{2} + 4 x y^{3} + y^{4})

= R e x^{4} + R e 4 x^{3} y + R e 6 x^{2} y^{2} + R e 4 x y^{3} + R e y^{4}

= e R x^{4} + 4 e R x^{3} y + 6 e R x^{2} y^{2} + 4 e R x y^{3} + e R y^{4}
