Masukan Anda
Temukan $$$\frac{d}{dx} \left(\frac{1}{4 x}\right)$$$.
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 $$$c = \frac{1}{4}$$$ dan $$$f{\left(x \right)} = \frac{1}{x}$$$:
$${\color{red}\left(\frac{d}{dx} \left(\frac{1}{4 x}\right)\right)} = {\color{red}\left(\frac{\frac{d}{dx} \left(\frac{1}{x}\right)}{4}\right)}$$Terapkan aturan pangkat $$$\frac{d}{dx} \left(x^{n}\right) = n x^{n - 1}$$$ dengan $$$n = -1$$$:
$$\frac{{\color{red}\left(\frac{d}{dx} \left(\frac{1}{x}\right)\right)}}{4} = \frac{{\color{red}\left(- \frac{1}{x^{2}}\right)}}{4}$$Dengan demikian, $$$\frac{d}{dx} \left(\frac{1}{4 x}\right) = - \frac{1}{4 x^{2}}$$$.
Jawaban
$$$\frac{d}{dx} \left(\frac{1}{4 x}\right) = - \frac{1}{4 x^{2}}$$$A
