Answer:

dx³+1/x³+9/dx = 3x² - 3x⁻⁴

Explanation:

y=x³+1/x³+9

 =x³+x⁻³+9

dx³/dx = 3x² [dxⁿ/dx = nxⁿ⁻¹]

dx⁻³/dx = -3x⁻⁴ [dxⁿ/dx = nxⁿ⁻¹]

d9/dx = 0 [Differentiation of constant is always 0]

dx³+1/x³+9/dx = 3x² - 3x⁻⁴+0

Answer:

 \\ \frac{dy}{dx}  = 3 {x}^{2}   -  \frac{3}{({x}^{ 4})}  \\

Explanation:

we \:  \: know \:  \: that \:  \:   \\ \\   \frac{d {x}^{n} }{dx}  = n {x}^{n - 1}  \\  \\  \:  \: therefore \:  \: we  \: \: can \:  \: write \:  \: the \: \\  \: equation \: \: as \\  \\ y =  {x}^{3}  +  {x}^{ - 3}  + 9 \\  \\ so \\  \\  \frac{dy}{dx}  = 3 {x}^{2}   + ( - 3) {x}^{ - 4}  + 0 \\  \\ (derivative \: of \: constant \: is \: 0) \\  \\  \frac{dy}{dx}  = 3 {x}^{2}   -  \frac{3}{ ({x}^{4} )}

I hope you are clear if not just comment me and mark me as the brainliest.
