limit as n approaches infinity of 7n^{5/4}

Lösung

n \to \infty lim (7 n^{\frac{5}{4}})

\infty

Schritte zur Lösung

n \to \infty lim (7 n^{\frac{5}{4}})

x \to a lim [c \cdot f (x)] = c \cdot x \to a lim f (x)

= 7 \cdot n \to \infty lim (n^{\frac{5}{4}})

x \to a lim [f (x)]^{b} = [x \to a lim f (x)]^{b}

mit Einschränkung des unbestimmten Ausdrucks

= 7 (n \to \infty lim (n))^{\frac{5}{4}}

Wende die allgemeine Grenze an:

n \to \infty lim (n) = \infty

= 7 \infty^{\frac{5}{4}}
