a^2=81

Lösung

a^{2} = 81

a = 9, a = - 9

Schritte zur Lösung

a^{2} = 81

Für

x^{2} = f (a)

sind die Lösungen

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

a = 81, a = - 81

81 = 9

- 81 = - 9

a = 9, a = - 9

f a c t or x^{4} + 4 x^{3} - 64 x - 256

x^{2} = 0.25

194 = 9 x + 68

x - 8 = 3 x + 2

\frac{( x + 2 ) ^{2}}{( x - 3 ) ( x - 7 )} \leq 0
