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

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

(7+3sqrt5)/(7-3sqrt5)=

(2sqrt(7))/(sqrt(5)-sqrt(3))

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))

Evaluate |[sqrt(3), sqrt(5)],[-sqrt(5), 3sqrt(3)]|

(30)/(5sqrt(3)-3sqrt(5))

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