x^{100}=0.31

Lösung

x^{100} = 0.31

x = \frac{100 31}{50 10}, x = - \frac{100 31}{50 10}

Dezimale

x = 0.98835 \dots, x = - 0.98835 \dots

Schritte zur Lösung

x^{100} = 0.31

Für

x^{n} = f (a)

, n ist gerade, die Lösungen sind

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

x = 100 0.31, x = - 100 0.31

100 0.31 = \frac{100 31}{50 10}

- 100 0.31 = - \frac{100 31}{50 10}

x = \frac{100 31}{50 10}, x = - \frac{100 31}{50 10}

x^{4} - 7 x^{2} + 2 x^{3} - x + 4 = 0

2 x^{4} + x^{3} - 11 x^{2} + x + 2 = 0

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

x^{3} + x - 1 = 0

- 16 r^{5} - 16 r^{4} + r + 1 = 0
