1m^2=81

Lösung

1 m^{2} = 81

m = 9, m = - 9

Schritte zur Lösung

1 \cdot m^{2} = 81

Multipliziere:

1 \cdot m^{2} = m^{2}

m^{2} = 81

Für

x^{2} = f (a)

sind die Lösungen

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

m = 81, m = - 81

81 = 9

- 81 = - 9

m = 9, m = - 9

45 x^{2} + 10 x = 0

4 k^{2} + 15 = 16 k

X^{2} - 3 X - 7 = 0

121 x^{2} - 132 x + 36 = 0

(n + 10) + 2 (n + 2) + (n + 4)^{2} = 1984
