((N+1)!)/((N-1)!)=56

Lösung

\frac{( N + 1 ) !}{( N - 1 ) !} = 56

N = 7, N = - 8

Schritte zur Lösung

\frac{( N + 1 ) !}{( N - 1 ) !} = 56

Vereinfache

\frac{( N + 1 ) !}{( N - 1 ) !} : N (N + 1)

N (N + 1) = 56

Löse

N (N + 1) = 56 : N = 7, N = - 8

N = 7, N = - 8

\frac{9}{1} = \frac{100}{x}

305 = \frac{1}{x ( 175 )}

2 = \frac{x + 11}{x - 9}

i = \frac{p n}{p n + 1}
