Differentiate

y = 3x + π^3
dy/dx=3(1)+0=3
y = 1 / (x-3)^3
y=〖(x-3)〗^(-3)
dy/dx=-3(x-3)^(-4) (1)=(-3)/〖(x-3)〗^4
y = (x^4 - x)^3 (3x + 2)^4
dy/dx=(x^4-x)^3 (4) (3x+2)^3 (3)+(3x+2)^4 (3) (x^4-x)^2 (4x^3-1)
dy/dx=12(x^4-x)^3 (3x+2)^3+3(3x+2)^4 (x^4-x)^2 (4x^3-1)
Note that this can be simplified further
dy/dx=3(x^4-x)^2 (3x+2)^3 [4(x^4-x)+(3x+2)(4x^3-1)]
dy/dx=3(x^4-x)^2 (3x+2)^3 (16x^4+8x^3-7x-2)
y = (1 + x  x^3)^4
dy/dx=〖4(1+x-x^3 )〗^3 (1-3x^2)
Compute the following ...
