Masukan Anda
Temukan $$$\frac{d}{dx} \left(2 x^{3}\right)$$$.
Solusi
Terapkan aturan kelipatan konstanta $$$\frac{d}{dx} \left(c f{\left(x \right)}\right) = c \frac{d}{dx} \left(f{\left(x \right)}\right)$$$ dengan $$$c = 2$$$ dan $$$f{\left(x \right)} = x^{3}$$$:
$${\color{red}\left(\frac{d}{dx} \left(2 x^{3}\right)\right)} = {\color{red}\left(2 \frac{d}{dx} \left(x^{3}\right)\right)}$$Terapkan aturan pangkat $$$\frac{d}{dx} \left(x^{n}\right) = n x^{n - 1}$$$ dengan $$$n = 3$$$:
$$2 {\color{red}\left(\frac{d}{dx} \left(x^{3}\right)\right)} = 2 {\color{red}\left(3 x^{2}\right)}$$Dengan demikian, $$$\frac{d}{dx} \left(2 x^{3}\right) = 6 x^{2}$$$.
Jawaban
$$$\frac{d}{dx} \left(2 x^{3}\right) = 6 x^{2}$$$A
