If `x^2+y^2=t-1/t` , `x^4+y^4=t^2+1/t^2` then `x^3ydy/dx=`

If x^(2)+y^(2)=t-1/t andx^(4)+y^(4)=t^(2)+(1)/(t^(2)), then prove that (dy)/(dx)=(1)/(x^(3)y).

If x^(2)+y^(2) = t +1//t and x^(4) +y^(4) = t^(2) + 1//t^(2) then (dy)/(dx) =______________

If x^(2)+y^(2)=t-(1)/(t) and x^(4)+y^(4)=t^(2)+(1)/(t^(2)) then x^(3)y(dy)/(dx)=(a)0(b)1(c)-1(d) non of these

if x^(2)+y^(2)=t-(1)/(t) and x^(4)+y^(4)=t^(2)+(1)/(t^(2)) then x^(3)y(dy)/(dx)=?

If x^(2)+y^(2)=t+(1)/(t) and x^(4)+y^(4)=t^(2)+(1)/(t^(2)) then (dy)/(dx)=

if x^(2)+y^(2)=t-(1)/(t) and x^(4)+y^(4)=t^(2)+(1)/(t^(2)) then prove that (dy)/(dx)=(1)/(x^(3)y)

If x^(2)+y^(2)=t-(1)/(t) and x^(4)+y^(4)=t^(2)+(1)/(t^(2)) then prove that (dy)/(dx)=(1)/(x^(3)y)

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