[x-y=13],[sqrt(x)+sqrt(y)=13]

sqrt(x/y) + sqrt(y/x) = 6

(x - y) / (sqrt(x)- sqrt(y)) = ____

If 0

If y=cos^(-1){(2x-3sqrt(1-x^(2)))/(sqrt(13))}, find (dy)/(dx)

If y=cos^(-1){(2x-3sqrt(1-x^2))/(sqrt(13))},"f i n d"(dy)/(dx)

Solve the equation: (sqrt(x+13)+sqrt(x-1))/(sqrt(x+13)-sqrt(x-1))=3 solution is {3/17}If true then enter 1 and if false then enter 0

(sqrt(x)-sqrt(y))(sqrt(x)+sqrt(y)) = ……………..

(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) =
