x^2=7^8

Lösung

x^{2} = 7^{8}

x = 2401, x = - 2401

Schritte zur Lösung

x^{2} = 7^{8}

7^{8} = 5764801

x^{2} = 5764801

Für

x^{2} = f (a)

sind die Lösungen

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

x = 5764801, x = - 5764801

5764801 = 2401

- 5764801 = - 2401

x = 2401, x = - 2401

(x + 2)^{2} + 25 = 50

so l v e f or x, x^{2} = 4 p (x) y

so l v e f or y, x^{2 x + 3} = y^{2} + 1

4 (x + 2)^{2} + 4 = 40

\frac{( 2 x ^{2} + 7 )}{3} = 13
