Expand by using suitable identity:
`(sqrt{5}-sqrt{3})^2`

Using suitable identity, evaluate: (104)^(3)

Using suitable identity, evaluate: (97)^(3)

2sqrt5 - sqrt5 = sqrt5

Simplify each of the following by rationalising the denominator: (7+3sqrt(5))/(7-3sqrt(5)) (ii) (2\ sqrt(3)-\ sqrt(5))/(2sqrt(2)+\ 3sqrt(3))

solve (3sqrt5 +sqrt3)/(sqrt5 -sqrt3)

(3+sqrt5)^2 xx (3-sqrt5)^2 = ?

Find (sqrt 3 - sqrt 5)(sqrt 5+ sqrt3)

Rationalize the denominatior of : (3)/(sqrt(5)+sqrt(2))

Simplify (sqrt5-sqrt2)(sqrt5+sqrt2)

Find : (sqrt5+sqrt2)(sqrt3+sqrt2)
