Question: Find the Derivative of 4/x.

Answer: We can express 4/x as 2x-1 by the rule of indices. So the derivative of 4/x is -4/x² by the power rule of derivatives.

Explanation:

$\dfrac{d}{dx}(\dfrac{4}{x})$ = $4 \dfrac{d}{dx}(\dfrac{1}{x})$

= $4 \dfrac{d}{dx}(x^{-1})$

= 4 × (-x-1-1) by the power rule of derivatives d/dx(xn) = nxn-1.

= -4 x-2

= $- \dfrac{4}{x^2}$.

Therefore, the derivative of 4/x is equal to -4/x2, and this is obtained by the power rule of derivatives.
