The derivative of 1/xn (1 by x power n) is equal to -n/xn+1. Here we learn how to find the derivative of 1 divided by x to the n.
The derivative formula of 1/x^n is given by
$\dfrac{d}{dx} \big( \dfrac{1}{x^n}\big) = -\dfrac{n}{x^{n+1}}$.
Derivative of 1/xn
Answer: The derivative of 1/xn is equal to -n/xn+1.
Explanation:
By the rule of indices, we have that
1/xn = x-n
Differentiating both sides, we get that
$\dfrac{d}{dx} \big( \dfrac{1}{x^n}\big)$
= $\dfrac{d}{dx} \big( x^{-n} \big)$
= -n x-n-1 by the power rule of derivatives
= $-\dfrac{n}{x^{n+1}}$.
So the derivative of 1 by x to the power n is equal to -n/xn+1, and this is obtained by the power rule of derivatives.
