Simplify `(sqrt(7)+sqrt(3))/(sqrt(7)-sqrt(3))+(sqrt(7)-sqrt(3))/(sqrt(7)+sqrt3)+(sqrt(3)-1)/(sqrt(3)+1)+(sqrt(3)+1)/(sqrt(3)-1)`

(sqrt(7)+sqrt(3))/(sqrt(7)-sqrt(3))-(sqrt(7)-sqrt(3))/(sqrt(7)+sqrt(3))

(sqrt(5)+sqrt(3))(sqrt(7)-sqrt(3))

Simplify (sqrt(7)+sqrt(3))(3-sqrt(3))

(sqrt(2)(2+sqrt(3)))/(sqrt(3)(sqrt(3)+1))-(sqrt(2)(2-sqrt(3)))/(sqrt(3)(sqrt(3)-1))

Simplify (1)/(sqrt(7)+sqrt(3)-sqrt(2))

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

(sqrt(7)-sqrt(5))^3 - (sqrt(7)+sqrt(5))^3

Simplify (sqrt(7))/(sqrt(2))+(3)/(sqrt(3))
