The value of f(x,y)=((4sqrt(x^(3)y)-4sqrt(x^(3)))/(sqrt(y)-sqrt(x))+(1+sqrt(xy))/(4sqrt(xy)))^(-2)(1+2sqrt((y)/(x))+(y)/(x))^((1)/(2)) when x=9,y=0.04

If x sqrt(1+y)+y sqrt(1+x)=0 and x!=y ,then (1+x)^(2)(dy)/(dx)+(3)/(2)=

If sqrt(x) + sqrt(y) = sqrt(a) , then (dy)/(dx) = 1/(2sqrt(x)) + 1/(2sqrt(y)) = 1/(2sqrt(a))

sqrt(1-x^(2))+sqrt(1-y^(2))=a(x-y), provethat (dy)/(dx)=sqrt((1-y^(2))/(1-x^(2)))

If y=log(sqrt(x)+(1)/(sqrt(x)))^(2), then , x(x+1)^(2)y_(2)+(x+1)^(2)y_(1) is
