The derivative of e^{1/x} is $-\frac{1}{x^2} e^{1/x}$. In this post, we will learn how to differentiate e to the power 1/x.

## Derivative of e^{1/x}

**Question:** What is the derivative of e raised to 1/x?

*Answer:* The derivative of e raised to 1/x is equal to $-1/x^2 e^{1/x}$.

**Explanation:**

We will find the derivative of $e^{\dfrac{1}{x}}$ by the chain rule method of derivatives. The following steps to be followed.

**Step 1:** Let us put $z=1/x$

**Step 2:** We have $\dfrac{dz}{dx}=-1/x^2$

**Step 3:** Then by the chain rule, the derivative of e to the power 1/x^2 is given by

$\dfrac{d}{dx}(e^{1/x^2})$ $=\dfrac{d}{dz}(e^z) \times \dfrac{dz}{dx}$

$=e^z \times (-\dfrac{1}{x^2})$

$=-\dfrac{1}{x^2} e^{1/x}$ as we have z=1/x.

**Conclusion:** So the derivative of e^{1/x} is equal to $-\dfrac{1}{x^2}$ e^{1/x}.
