Question

differentiate with respect x to x​

Answer 1

Answer:

given x^4 - 2x + 1/x^2

dy/dx = x^4 - 2x + x^-2

= 4x^3 - 2 - 2x^-3

= 4x^3 - 2/x^3 - 2

= 2 [ 2x^3 - 1/x^3 - 1 ]

[ power rule d/dx(x^n = nx^(n-1) ]

Answer 2

Formula used : Power Rule

$\large{\underline{\boxed{\sf{\dfrac{d(x^n)}{dx}\ =\ nx^{n\ -\ 1}}}}}$
