limit as x approaches 0 of (1+7x)^{1/x}

x \to 0 lim ((1 + 7 x)^{\frac{1}{x}})

e^{7}

Decimal Notation

1096.63315 \dots

Solution steps

x \to 0 lim ((1 + 7 x)^{\frac{1}{x}})

Apply exponent rules

= x \to 0 lim (e^{\frac{1}{x} l n (1 + 7 x)})

Apply the Limit Chain Rule:

e^{7}

= e^{7}

\int \frac{( y + 1 )}{y ^{2} + y + 1} d y

\int \frac{5 + x + x ^{2}}{x} d x

\int \frac{2 x + 11}{x ^{2} + 4 x + 5} d x

\frac{\partial}{\partial x} (8 x^{2} y - 3)

What is the limit as x approaches 0 of (1+7x)^{1/x} ?
