Lösung

erweitern

(3 x^{2} + 18 x + 27) (x + 3)^{\frac{1}{5}}

(x + 3)^{\frac{1}{5}} \cdot 3 x^{2} + (x + 3)^{\frac{1}{5}} \cdot 18 x + (x + 3)^{\frac{1}{5}} \cdot 27

Schritte zur Lösung

(3 x^{2} + 18 x + 27) (x + 3)^{\frac{1}{5}}

= (x + 3)^{\frac{1}{5}} (3 x^{2} + 18 x + 27)

Wende das Distributivgesetz an:

m (a + b + c) = ma + mb + m c

(x + 3)^{\frac{1}{5}} (3 x^{2} + 18 x + 27) = (x + 3)^{\frac{1}{5}} \cdot 3 x^{2} + (x + 3)^{\frac{1}{5}} \cdot 18 x + (x + 3)^{\frac{1}{5}} \cdot 27

= (x + 3)^{\frac{1}{5}} \cdot 3 x^{2} + (x + 3)^{\frac{1}{5}} \cdot 18 x + (x + 3)^{\frac{1}{5}} \cdot 27
