limit as x approaches infinity of (1-1/(4x))^{8x}

x \to \infty lim ((1 - \frac{1}{4 x})^{8 x})

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

Decimal

0.13533 \dots

Solution steps

x \to \infty lim ((1 - \frac{1}{4 x})^{8 x})

Apply exponent rules

= x \to \infty lim (e^{8 x l n (1 - \frac{1}{4 x})})

Apply the Limit Chain Rule:

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

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