`y = (2x+3)^4 - (7x-1)^2 + 2/(3x-1)^3 + 4/(3x-2)^3 , dy/dx`

y=(2x+3)^(4)-(7x-1)^(2)+(2)/((3x+1)^(3))+(4)/((4x-3)^(2)) . Find (dy)/(dx)

y=(2x+3)^(4)-(7x-1)^(2)+(2)/((3x+1)^(3))+(4)/((4x-3)^(2)) . Find (dy)/(dx)

If y = sqrt(((x-3)(x^2+4))/((3x^2 + 4x + 5)) , then find dy/dx

If y = tan ^(-1) ((2x )/( 1 -x ^(2))) + tan ^(-1) ((3x - x ^(3))/( 1 - 3x ^(2)))- tan ^(-1) ((4x - 4x ^(3))/( 1 - 6x + x ^(4))), then show that (dy)/(dx) = (1)/(1 + x ^(2)).

If (x+1) /( (x+2) ^(2) (x+3) ^(4)),then (dy)/(dx) =
