c^2=40^2+9^2

Lösung

c^{2} = 4 0^{2} + 9^{2}

c = 41, c = - 41

Schritte zur Lösung

c^{2} = 4 0^{2} + 9^{2}

Vereinfache

4 0^{2} + 9^{2} : 1681

Für

x^{2} = f (a)

sind die Lösungen

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

c = 1681, c = - 1681

1681 = 41

- 1681 = - 41

c = 41, c = - 41

so l v e f or d, V = 5 d^{2}

23 u^{2} + 40 u = 0
