" 15.Simplify: "(((3)/(2+sqrt(3))-(2)/(2-sqrt(3))))/(2-5sqrt(3))

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

Simplify :- (2+sqrt(3))^(5)+(2-sqrt(3))^(5)

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

Simplify : (3) / ( 5- sqrt3) + (2)/(5+ sqrt3)

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

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

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

Rationales the denominator and simplify: (sqrt(3)-sqrt(2))/(sqrt(3)+sqrt(2)) (ii) (5+2sqrt(3))/(7+4sqrt(3)) (iii) (1+sqrt(2))/(3-2sqrt(2)) (2sqrt(6)-sqrt(5))/(3sqrt(5)-2sqrt(6)) (v) (4sqrt(3)+5sqrt(2))/(sqrt(48)+sqrt(18)) (vi) (2sqrt(3)-sqrt(5))/(2sqrt(3)+3sqrt(3))

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