Continuity and Differentiability

Question:

Derivative of $e^{2x}$ with respect to $e^x$ is:

Options:

$e^x$

$2e^x$

$2e^{2x}$

$2e^{3x}$

Correct Answer:

$2e^x$

Explanation:

The correct answer is Option (2) → $2e^x$ ##

Let $u = e^{2x}, v = e^x$.

$\frac{du}{dx} = e^{2x} \cdot 2, \quad \frac{dv}{dx} = e^x$

$\frac{du}{dv} = \frac{\frac{du}{dx}}{\frac{dv}{dx}} = \frac{2e^{2x}}{e^x} = 2e^x$
