x^2= 49/81

Lösung

x^{2} = \frac{49}{81}

x = \frac{7}{9}, x = - \frac{7}{9}

Dezimale

x = 0.77777 \dots, x = - 0.77777 \dots

Schritte zur Lösung

x^{2} = \frac{49}{81}

Für

x^{2} = f (a)

sind die Lösungen

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

x = \frac{49}{81}, x = - \frac{49}{81}

\frac{49}{81} = \frac{7}{9}

- \frac{49}{81} = - \frac{7}{9}

x = \frac{7}{9}, x = - \frac{7}{9}

2 < 1 - 4 x \leq 8

s im pl i f y \frac{4}{5} + 3

3 x + 2 = 32

8 x^{2} + 3 = 10 x

\frac{g}{2.1} = - 6.8
