x^{10}=0.9

Lösung

x^{10} = 0.9

x = \frac{5 3}{10 10}, x = - \frac{5 3}{10 10}

Dezimale

x = 0.98951 \dots, x = - 0.98951 \dots

Schritte zur Lösung

x^{10} = 0.9

Für

x^{n} = f (a)

, n ist gerade, die Lösungen sind

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

x = 10 0.9, x = - 10 0.9

10 0.9 = \frac{5 3}{10 10}

- 10 0.9 = - \frac{5 3}{10 10}

x = \frac{5 3}{10 10}, x = - \frac{5 3}{10 10}

x^{3} + 5 x + 17 = 59

(x - 2)^{2} (x + 2) = (x + 1) (x + 5)

r^{7} = \frac{1}{1.5}

4 x^{3} + 5 x - 6 = 0

x^{5} + 4 x^{4} + 3 x^{2} + 4 = 0
