If `x= sqrt5+sqrt3` and `y = sqrt5-sqrt3`, then `x^4 -y^4`

(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) =

If x=(5-sqrt3)/(5+sqrt3) and y=(5+sqrt3)/(5-sqrt3) then show that x-y=-(10sqrt3)/11

If x=3sqrt(5)+2sqrt(2) and y=3sqrt(5)-2sqrt(2) , then the value of (x^(2)-y^(2))^(2) is

x+sqrt(5)=4+sqrt(y), then x+y=

If x= ( sqrt5- sqrt3)/ ( sqrt5+ sqrt3) and y= ( sqrt5+ sqrt3)/( sqrt5- sqrt3) find the value of x^(2) + y ^(2)

If 5 sqrt5 x^3-81 sqrt3 y^3 div sqrt5 x-3 sqrt3 y=Ax^2+By^2+Cxy , then the value of (6A+B-sqrt15 C) is: यदि 5 sqrt5 x^3-81 sqrt3 y^3 div sqrt5 x-3 sqrt3 y=Ax^2+By^2+Cxy है, तो (6A+B-sqrt15 C) का मान ज्ञात करें |

If x = (5-sqrt(3))/(5+sqrt(3)) and y = (5+sqrt(3))/(5-sqrt(3)) , show that x -y = - (10sqrt(3))/(11)
