limit as x approaches 0 of (1+ax)^{1/x}

x \to 0 lim ((1 + a x)^{\frac{1}{x}})

e^{a}

Solution steps

x \to 0 lim ((1 + a x)^{\frac{1}{x}})

Apply exponent rules

= x \to 0 lim (e^{\frac{1}{x} l n (1 + a x)})

Apply the Limit Chain Rule:

e^{a}

= e^{a}

\frac{d}{d x} ((1 + x^{2})^{\frac{1}{2}})

(6 x + e^{- x^{2}})^{4}

(\frac{1}{y ^{2}} - \frac{9}{y ^{4}}) (y - 7 y^{3})

\int_{a}^{b} 25 - x^{2} d x

3 sin (x) ln (x)
