|z+4|=16

Lösung

∣ z + 4 ∣ = 16

z = - 20 or z = 12

Schritte zur Lösung

∣ z + 4 ∣ = 16

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

z + 4 = - 16 or z + 4 = 16

z + 4 = - 16 or z + 4 = 16

z = - 20 or z = 12

6 = ∣ - 6 u ∣

x^{3} + ∣ x ∣ - 2 = 0

∣ 4 x + 6 ∣ - 1 = 21

∣ - 3 x - 6 ∣ = 5 x + 10

\frac{a}{7} = 33
