If `x=sqrt7-sqrt5` and `y=sqrt13-sqrt11` then

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

Which one is greater between (sqrt7 - sqrt5) and (sqrt13 - sqrt11) ?

If x=sqrt(11)-sqrt(10),y=sqrt(12)-sqrt(11), then

If x=sqrt(7)-sqrt(5),y=sqrt(5)-sqrt(3),z=sqrt(3)-sqrt(7) then find the value of x^(3)+y^(3)+z^(3)-2xyz

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

Do as directed: (i) Add : sqrt(125 + 2 sqrt(27) and - 5 sqrt(5) - sqrt(3) (ii) Add: sqrt(7) - sqrt(11) and sqrt(5) - sqrt(11) + sqrt(13) (iii) Multiply : 2 sqrt(2) by 5 sqrt(2) (iv) Multiply : (-3 + sqrt(5)) by 3 (v) Divide : 7 sqrt(5) by - 14 sqrt(125) Divide : 7 sqrt(5) by -14 sqrt(125) (vi) Divide : 2 sqrt(216) - 3 sqrt(27) by 3
