if `4/(2+sqrt(3)+sqrt(7))=sqrt(a)+sqrt(b)-sqrt(c)` then :

(sqrt(7)+2sqrt(3))(sqrt(7)-2sqrt(3))

sqrt(7+4sqrt3) - sqrt(7-4sqrt3) =

(3+sqrt(7))/(3-sqrt(7))=a+b sqrt(7)

4sqrt(3)-7sqrt(12)+2sqrt(75)=

(5+2sqrt(3))/(7+4sqrt(3))=a-b sqrt(3)

(5+2sqrt(3))/(7+4sqrt(3))=a-b sqrt(3)

If a=(sqrt(7)-sqrt(6))/(sqrt(7)+sqrt(6)) and b=(sqrt(7)+sqrt(6))/(sqrt(7)-sqrt(6)), then find the value of a^(2)+b^(2)+ab

If a=(sqrt(7)-sqrt(6))/(sqrt(7)+sqrt(6)) and b=(sqrt(7)+sqrt(6))/(sqrt(7)-sqrt(6)), then find the value of a^(2)+b^(2)+ab

Which of the following is equal to root(3)(-1)?(sqrt(3)+sqrt(-1))/(2) b.(-sqrt(3)+sqrt(-1))/(sqrt(-4)) c.(sqrt(3)-sqrt(-1))/(sqrt(-4))d.-sqrt(-1)

(sqrt(5)+sqrt(3))/(sqrt(5)-sqrt(3))+(sqrt(5)-sqrt(3))/(sqrt(5)+sqrt(3))+(sqrt(8)+sqrt(7))/(sqrt(8)-sqrt(7))-(sqrt(8)-sqrt(7))/(sqrt(8)+sqrt(7))=a+b sqrt(14) Find the value of (a-b) (a) 8, (b) 16 (c) 4, (d) 0
