Find $$$\frac{d}{dv} \left(2 v\right)$$$.
Solution
Apply the constant multiple rule $$$\frac{d}{dv} \left(c f{\left(v \right)}\right) = c \frac{d}{dv} \left(f{\left(v \right)}\right)$$$ with $$$c = 2$$$ and $$$f{\left(v \right)} = v$$$:
$${\color{red}\left(\frac{d}{dv} \left(2 v\right)\right)} = {\color{red}\left(2 \frac{d}{dv} \left(v\right)\right)}$$Apply the power rule $$$\frac{d}{dv} \left(v^{n}\right) = n v^{n - 1}$$$ with $$$n = 1$$$, in other words, $$$\frac{d}{dv} \left(v\right) = 1$$$:
$$2 {\color{red}\left(\frac{d}{dv} \left(v\right)\right)} = 2 {\color{red}\left(1\right)}$$Thus, $$$\frac{d}{dv} \left(2 v\right) = 2$$$.
Answer
$$$\frac{d}{dv} \left(2 v\right) = 2$$$A
