(n!)/((n-2)!)=56

Lösung

\frac{n !}{( n - 2 ) !} = 56

n = 8, n = - 7

Schritte zur Lösung

\frac{n !}{( n - 2 ) !} = 56

Vereinfache

\frac{n !}{( n - 2 ) !} : n (n - 1)

n (n - 1) = 56

Löse

n (n - 1) = 56 : n = 8, n = - 7

n = 8, n = - 7

\frac{1}{x} = \frac{1}{x - 5}

\frac{x}{x - 6} = \frac{x - 2}{- x + 6}

0.001 = (\frac{1}{1 + 0.5 x})^{2}

\frac{4}{5} = \frac{6}{b} - 1

25 = \frac{15 - 8 x}{8 x} \cdot 100
