b^2=1-1/(9^2)

Lösung

b^{2} = 1 - \frac{1}{9 ^{2}}

b = \frac{4 5}{9}, b = - \frac{4 5}{9}

Dezimale

b = 0.99380 \dots, b = - 0.99380 \dots

Schritte zur Lösung

b^{2} = 1 - \frac{1}{9 ^{2}}

Vereinfache

1 - \frac{1}{9 ^{2}} : \frac{80}{81}

Für

x^{2} = f (a)

sind die Lösungen

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

b = \frac{80}{81}, b = - \frac{80}{81}

\frac{80}{81} = \frac{4 5}{9}

- \frac{80}{81} = - \frac{4 5}{9}

b = \frac{4 5}{9}, b = - \frac{4 5}{9}

- x^{2} + 8 x - 8 = 0

p^{2} + 10 p + 1 = 0

x^{2} = \frac{5}{2}

2 (3 x - 1)^{2} = 32

16 - x^{2} = 16 - 8 x + x^{2}
