u^2=100

Lösung

u^{2} = 100

u = 10, u = - 10

Schritte zur Lösung

u^{2} = 100

Für

x^{2} = f (a)

sind die Lösungen

x = f (a), - f (a)

u = 100, u = - 100

100 = 10

- 100 = - 10

u = 10, u = - 10

so l v e f or x, x^{2} - 4 x y + 4 y^{2} + 55 y + 1 = 0

3 a x^{2} + 2 b x + 2 c = 0

so l v e f or x, 3^{y} = x^{2}

lo g_{10} (4) (x + 2) - lo g_{10} (16) (x^{2} - 4) = 1

2^{2} + b^{2} = 6^{2}
