limit as x approaches infinity of (x/(x+1))^{2x}

x \to \infty lim ((\frac{x}{x + 1})^{2 x})

\frac{1}{e ^{2}}

Decimal

0.13533 \dots

Solution steps

x \to \infty lim ((\frac{x}{x + 1})^{2 x})

Apply exponent rules

= x \to \infty lim (e^{2 x l n (\frac{x}{x + 1})})

Apply the Limit Chain Rule:

\frac{1}{e ^{2}}

= \frac{1}{e ^{2}}

What is the limit as x approaches infinity of (x/(x+1))^{2x} ?
The limit as x approaches infinity of (x/(x+1))^{2x} is 1/(e^2)
