Simplify `(4+sqrt5)(2-sqrt3)`

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

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

Simplify: (i) (3sqrt(2)-2sqrt(2))/(3sqrt(2)+\ 2sqrt(3))+(sqrt(12))/(sqrt(3)-\ sqrt(2)) (ii) (sqrt(5)+\ sqrt(3))/(sqrt(5)-\ sqrt(3))+(sqrt(5)-\ sqrt(3))/(sqrt(5)+\ sqrt(3))

Simplify: (sqrt3/2)^2 -(sqrt3)^2+(sqrt 2)^2 +1/2

Simplify: (2sqrt(2)+sqrt(3))/(2sqrt(2)-sqrt(3))

Rationlise the denominator and simplify: (1)/(2sqrt5-sqrt3)

Simplify : sqrt(3+2sqrt(2))

Simplify: sqrt(3-2sqrt(2))

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