erweitern x^{6/7}(x^2-5)

Lösung

erweitern

x^{\frac{6}{7}} (x^{2} - 5)

x^{\frac{20}{7}} - x^{\frac{6}{7}} \cdot 5

Schritte zur Lösung

x^{\frac{6}{7}} (x^{2} - 5)

Wende das Distributivgesetz an:

a (b - c) = ab - a c

x^{\frac{6}{7}} (x^{2} - 5) = x^{\frac{6}{7}} x^{2} - x^{\frac{6}{7}} \cdot 5

= x^{\frac{6}{7}} x^{2} - x^{\frac{6}{7}} \cdot 5

Vereinfache

x^{\frac{6}{7}} x^{2} : x^{\frac{20}{7}}

= x^{\frac{20}{7}} - x^{\frac{6}{7}} \cdot 5
