Differentiate the following w.r.t x
`x^(-4)`

Explanation

To differentiate the function \( x^{-4} \) with respect to \( x \), we will use the power rule of differentiation. The power rule states that if you have a function of the form \( x^n \), its derivative is given by:

\[ \frac{d}{dx}(x^n) = n \cdot x^{n-1} \]

Now, let's apply this step by step.
