[" 15.If "y=sqrt(6)-sqrt(3),h=sqrt(3)-sqrt(2)" and "r=sqrt(2)-sqrt(6)],[" then find the value of "a^(3)+b^(3)+c^(3)-2abc]

If quad sqrt(6)-sqrt(3),b=sqrt(3)-sqrt(2) and c=sqrt(2)-sqrt(6), then find the value of a^(3)+b^(3)+c^(3)-2abc.

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

If a=(sqrt(3)+sqrt(2))/(sqrt(3)-sqrt(2)) and b=(sqrt(3)-sqrt(2))/(sqrt(3)+sqrt(2)) , then find the value of 3(a^(2)-b^(2)) .

If x= (sqrt3+sqrt2)/(sqrt3-sqrt2) and y=(sqrt3-sqrt2)/(sqrt3+sqrt2) , then find the value of x^2+y^2

If a=(sqrt(3)-sqrt(2))/(sqrt(3)+sqrt(2)) and b=(sqrt(3)+sqrt(2))/(sqrt(3)-sqrt(2)), find the value of a^(2)+ab+b^(2)

If a=(sqrt(3)+sqrt(2))/(sqrt(3)-sqrt(2)),b=(sqrt(3)-sqrt(2))/(sqrt(3)+sqrt(2)) then the value of a+b is

find a and b (6)/(sqrt(3)-sqrt(2))=a sqrt(3)-b sqrt(2)

(sqrt(2)+sqrt(3))/(3sqrt(2)-2sqrt(3))=2-b sqrt(6) find b
