Question: Find the Derivative of 2/x.

Answer: We can express 2/x as 2x-1. So by the power rule, the derivative of 2/x is equal to -2/x².

Explanation:

$\dfrac{d}{dx}(\dfrac{2}{x})$

= $2 \dfrac{d}{dx}(\dfrac{1}{x})$

= $2 \dfrac{d}{dx}(x^{-1})$

= 2 × (-1 ⋅ x-1-1) by the power rule of derivatives d/dx(xn) = nxn-1.

= -2 × x-2

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

Hence, the derivative of 2/x is -2/x2, and this is obtained by the power rule of derivatives.
