x^2=0.81

Lösung

x^{2} = 0.81

x = \frac{9}{10}, x = - \frac{9}{10}

Dezimale

x = 0.9, x = - 0.9

Schritte zur Lösung

x^{2} = 0.81

Für

x^{2} = f (a)

sind die Lösungen

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

x = 0.81, x = - 0.81

0.81 = \frac{9}{10}

- 0.81 = - \frac{9}{10}

x = \frac{9}{10}, x = - \frac{9}{10}

x^{2} - 42 x + n = 0

- \frac{3}{2} x^{2} - 12 x + 54 = 0

f a c t or 8 x^{2} + 22 x + 15 = 0

- 16 t^{2} + 10 t + 6 = 0

so l v e f or x, 9 x^{2} - 4 y^{2} + 36 x + 24 y = 0
