$lim_{x \to 0} {(e^{a x} + x)}^{\frac{1}{x}}$

Step 1

Use the properties of logarithms to simplify the limit.

Step 1.1

Rewrite ${(e^{a x} + x)}^{\frac{1}{x}}$ as $e^{\ln ({(e^{a x} + x)}^{\frac{1}{x}})}$ .

$lim_{x \to 0} e^{\ln ({(e^{a x} + x)}^{\frac{1}{x}})}$

Step 1.2

Expand $\ln ({(e^{a x} + x)}^{\frac{1}{x}})$ by moving $\frac{1}{x}$ outside the logarithm.

$lim_{x \to 0} e^{\frac{1}{x} \ln (e^{a x} + x)}$

Step 2

Because there are no values to the left of $0$ in the domain of $e^{\frac{1}{x} \ln (e^{a x} + x)}$ , the limit does not exist.
