" 3."sqrt(x)+sqrt(y)=4

If sqrt(x) + sqrt(y) = sqrt(5) , Prove that (dy)/(dx) = (-3)/(2) when x= 4" and "y=9 .

Solve for x and y : 2/sqrt(x) + 3/sqrt(y) = 2 4/sqrt(x) + 9/sqrt(y) = -1

Solve the following pairs of equations by reducing them to a pair of linear equations. 2/sqrt(x)+3/sqrt(y)=2 4/sqrt(x)-9/sqrt(y)=-1

(sqrt(x)+sqrt(y))^(2)=x+y+2sqrt(xy) and sqrt(x)sqrt(y)=sqrt(xy) , where x and y are positive real numbers . If x=2sqrt(5)+sqrt(3) and y=2sqrt(5)-sqrt(3) , then x^(4)+y^(4) =

Solve the following equations:- sqrt(3x)+sqrt(2y)=sqrt(3) sqrt(5x)+sqrt(3y)=sqrt(3)

sqrt (2x) -sqrt (3y) = 0sqrt (3x) -sqrt (3y) = 0

The length of subtangent to sqrt(x)+sqrt(y)=3 at (4, 1) is

Solution of the equations sqrt2x+sqrt3y=0 and sqrt(3x)-sqrt(8y)=0

Solve the following system of equations: 2/(sqrt(x))+3/(sqrt(y))=2,\ \ \ \ 4/(sqrt(x))-9/(sqrt(y))=-1
