0

Schritte zur Lösung

x \to \infty lim (\frac{x - 2 ^{x}}{3 ^{x} - 5})

Dividiere durch

3^{x} : \frac{\frac{x}{3 ^{x}} - ( \frac{2}{3} ) ^{x}}{1 - \frac{5}{3 ^{x}}}

= x \to \infty lim (\frac{\frac{x}{3 ^{x}} - ( \frac{2}{3} ) ^{x}}{1 - \frac{5}{3 ^{x}}})

x \to a lim [\frac{f ( x )}{g ( x )}] = \frac{lim _{x \to a} f ( x )}{lim _{x \to a} g ( x )}, x \to a lim g (x) \neq = 0

mit Einschränkung des unbestimmten Ausdrucks

= \frac{lim _{x \to \infty} ( \frac{x}{3 ^{x}} - ( \frac{2}{3} ) ^{x} )}{lim _{x \to \infty} ( 1 - \frac{5}{3 ^{x}} )}

x \to \infty lim (\frac{x}{3 ^{x}} - (\frac{2}{3})^{x}) = 0

x \to \infty lim (1 - \frac{5}{3 ^{x}}) = 1

= \frac{0}{1}
