erweitern (2,3i)(2,-3i)

Lösung

erweitern

(2, 3 i) (2, - 3 i)

2 (2 \cdot 3 i,), - 3 i (2 \cdot 3 i,)

Schritte zur Lösung

(2, 3 i) (2, - 3 i)

= (2 \cdot 3 i,) (2, - 3 i)

Wende das Distributivgesetz an:

a (b - c) = ab - a c

a = (2, 3 i), b = 2,, c = 3 i

= (2, 3 i) \cdot 2, - (2, 3 i) \cdot 3 i

= 2 (2 \cdot 3 i,), - 3 i (2 \cdot 3 i,)
