" 1.If "(1)/(sqrt(2)+sqrt(3)-sqrt(5))=a sqrt(2)+b sqrt(3)+c sqrt(30)" .Find "a,b" and "c" ."

if (1)/(sqrt(2)+sqrt(3)+sqrt(5))=a sqrt(2)+b sqrt(3)+c sqrt(30) then value of a+b+c is (where a,b,c are rational numbers)

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

[(1)/(sqrt(2)+sqrt(3)-sqrt(5))+(1)/(sqrt(2)-sqrt(3)-sqrt(5))] in simplified form equals (a) 0 (b) (1)/(sqrt(2)) (c) 1 (c) sqrt(2)

If (5 sqrt 2+3 sqrt 3)-(6 sqrt 2-7 sqrt 3)=a sqrt 2+b sqrt 3 then find a and b.

If a=(sqrt(3)-sqrt(2))/(sqrt(3)+sqrt(2)) and b=(sqrt(3)+sqrt(2))/(sqrt(3)-sqrt(2)) then find a^(2)+b^(2)-5ab

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 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 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 a = (sqrt(3) - sqrt(2))/(sqrt(3) + sqrt(2)) and b = (sqrt(3) + sqrt(2))/(sqrt(3) - sqrt(2)) then value of sqrt(3a^2 - 5ab + 3b^2) is

The value of sqrt(5+2sqrt(6)) is (a) sqrt(3)-sqrt(2) (b) sqrt(3)+sqrt(2) (c) sqrt(5)+sqrt(6) (d) none of these
