Simiplify `10sqrt(5)-7sqrt(5) + 3sqrt(5)`

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

Simplify: (3sqrt7)/(sqrt5 + sqrt2) - (5 sqrt5)/(sqrt2 + sqrt7) + (2 sqrt2)/(sqrt7 + sqrt5)

Simiplify : (sqrt((5+12i)) + sqrt((5-12i)))/(sqrt((5+12i))-sqrt((5-12i)))

Simplify: (7sqrt(3))/(sqrt(10)+sqrt(3))-(2sqrt(5))/(sqrt(6)+sqrt(5))-(3sqrt(2))/(sqrt(15)+3sqrt(2))

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))

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

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

Simiplify : sqrt(-64).(3 + sqrt(-361))

(sqrt7-sqrt5)/(sqrt7+sqrt5)
