solvefor x,f^n(x)=sqrt(x)

Lösung

löse nach

x, f^{n} (x) = x

x = \frac{1}{f ^{2 n}}, x = 0

Schritte zur Lösung

f^{n} (x) = x

Quadriere beide Seiten:

x^{2} f^{2 n} = x

x^{2} f^{2 n} = x

Löse

x^{2} f^{2 n} = x : x = \frac{1}{f ^{2 n}}, x = 0

x = \frac{1}{f ^{2 n}}, x = 0

\frac{2}{11 - x} = 1

x + 9 + 3 = x

36 - 3 x - 45 = 30

15 - 3 x = x + 1

x^{(\frac{4}{3})} = 81
