सरल कीजिए :
`(3+sqrt(-5))(3-sqrt(-5))`

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

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

(sqrt(5)-2)(sqrt(3)-sqrt(5))

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

(sqrt3-sqrt5)(sqrt5+sqrt3)

(2sqrt3+sqrt5)(2sqrt3+sqrt5)

4 sin 27^(0)= 1) sqrt(5+sqrt(5))+sqrt(3-sqrt(5)) 2) sqrt(5-sqrt(5))+sqrt(3+sqrt(5) 3) sqrt(5+sqrt(5))-sqrt(3-sqrt(5)) 4) sqrt(5+sqrt(5))+sqrt(3+sqrt(5)
