(n!)/((n-2)!)=240

Lösung

\frac{n !}{( n - 2 ) !} = 240

n = 16, n = - 15

Schritte zur Lösung

\frac{n !}{( n - 2 ) !} = 240

Vereinfache

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

n (n - 1) = 240

Löse

n (n - 1) = 240 : n = 16, n = - 15

n = 16, n = - 15

\frac{3}{2 x - 4} = 0.5

\frac{2 x - 1}{3} = \frac{1}{5 - x}

(\frac{( x ^{1} ) ^{2} + 1}{( x ^{1} ) ^{2}}) = 8

\frac{7.2}{x + 2} = \frac{x - 2}{3.2}

so l v e f or x, f + \frac{1}{x} \cdot f (- x) = 2 x
