Dividiere durch

e^{3 x} : \frac{\frac{3 x}{e ^{3 x}} + \frac{2}{e ^{2 x}}}{\frac{4 x}{e ^{3 x}} - 1}

= x \to \infty lim (\frac{\frac{3 x}{e ^{3 x}} + \frac{2}{e ^{2 x}}}{\frac{4 x}{e ^{3 x}} - 1})

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{3 x}{e ^{3 x}} + \frac{2}{e ^{2 x}} )}{lim _{x \to \infty} ( \frac{4 x}{e ^{3 x}} - 1 )}

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

x \to \infty lim (\frac{4 x}{e ^{3 x}} - 1) = - 1

= \frac{0}{- 1}
