Question

derivation of standard function X rays power 4

Answer 1

hey ✌

$if \: y = {x}^{4} \\ \frac{d}{dx} y = \frac{d}{dx} {x}^{4} \\using \: identity \: \: {x}^{n} = {nx}^{n - 1} \\ \frac{d}{dx} {x}^{4} = 4 {x}^{3}$

hope it helps u ☝
please mark as brainliest ✔

Answer 2

 d/dx (x^n)=n*x^(n-1) 
so, 4x^3
hope it helps
