Your Input

Find $\frac{d}{dx} \left(e^{x y z}\right)$ .

Solution

The function $e^{x y z}$ is the composition $f{\left(g{\left(x \right)} \right)}$ of two functions $f{\left(u \right)} = e^{u}$ and $g{\left(x \right)} = x y z$ .

Apply the chain rule $\frac{d}{dx} \left(f{\left(g{\left(x \right)} \right)}\right) = \frac{d}{du} \left(f{\left(u \right)}\right) \frac{d}{dx} \left(g{\left(x \right)}\right)$ :

{\color{red}\left(\frac{d}{dx} \left(e^{x y z}\right)\right)} = {\color{red}\left(\frac{d}{du} \left(e^{u}\right) \frac{d}{dx} \left(x y z\right)\right)}

The derivative of the exponential is $\frac{d}{du} \left(e^{u}\right) = e^{u}$ :

{\color{red}\left(\frac{d}{du} \left(e^{u}\right)\right)} \frac{d}{dx} \left(x y z\right) = {\color{red}\left(e^{u}\right)} \frac{d}{dx} \left(x y z\right)

Return to the old variable:

e^{{\color{red}\left(u\right)}} \frac{d}{dx} \left(x y z\right) = e^{{\color{red}\left(x y z\right)}} \frac{d}{dx} \left(x y z\right)

Apply the constant multiple rule $\frac{d}{dx} \left(c f{\left(x \right)}\right) = c \frac{d}{dx} \left(f{\left(x \right)}\right)$ with $c = y z$ and $f{\left(x \right)} = x$ :

e^{x y z} {\color{red}\left(\frac{d}{dx} \left(x y z\right)\right)} = e^{x y z} {\color{red}\left(y z \frac{d}{dx} \left(x\right)\right)}

Apply the power rule $\frac{d}{dx} \left(x^{n}\right) = n x^{n - 1}$ with $n = 1$ , in other words, $\frac{d}{dx} \left(x\right) = 1$ :

y z e^{x y z} {\color{red}\left(\frac{d}{dx} \left(x\right)\right)} = y z e^{x y z} {\color{red}\left(1\right)}

Thus, $\frac{d}{dx} \left(e^{x y z}\right) = y z e^{x y z}$ .

Answer

$\frac{d}{dx} \left(e^{x y z}\right) = y z e^{x y z}$ A
