Simplify `x=(sqrt5-1)/(sqrt5+1)`

Simplify: (5+sqrt5)(5-sqrt5)

Simplify (sqrt5 - sqrt3)(sqrt5 + sqrt 3)

Simplify: (sqrt(5)-2)/(sqrt(5)+2)-(sqrt(5)+2)/(sqrt(5)-2)

If sqrt(5)=2.236 then simplify sqrt((sqrt(5)-1)/(sqrt(5)+1))

Simplify: (7+3sqrt(5))/(3+sqrt(5))-(7-3sqrt(5))/(3-sqrt(5)) (ii) (1)/(2+sqrt(3))+(2)/(sqrt(5)-sqrt(3))+(1)/(2-sqrt(5))

Simplify: (4+sqrt(5))/(4-sqrt(5))+(4-sqrt(5))/(4+sqrt(5))

Simplify (3+sqrt5)/(sqrt7-sqrt3)

Simplify (2+sqrt3)/(sqrt5+sqrt2)

Simplify (5+sqrt(2))(3+sqrt(5))

simplify :(4+sqrt(5))/(4-sqrt(5))+(4-sqrt(5))/(4+sqrt(5))
