Evaluate :

`( 2 - sqrt5 )/ ( 2 + sqrt5 ) + ( 2 +sqrt5 )/ ( 2 - sqrt5 ) `

Evaluate : ( sqrt(5) - 2 )/ ( sqrt ( 5 ) +2 ) + ( sqrt(5) + 2 )/ ( sqrt ( 5 ) - 2 )

Evaluate : ( 3 + sqrt5 )^2 times (3- sqrt5)^2 = ?

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

Evaluate : ( sqrt5 - sqrt2 ) times ( sqrt5 + sqrt2 )

Evaluate : ( sqrt(5) + sqrt(2) ) times ( sqrt(5) + sqrt(2) )

Evaluate : ( sqrt(2) - sqrt(3) + sqrt(5) )times ( sqrt(2) + sqrt(3) + sqrt(5) )

Find ( sqrt(5) + 1 )/( sqrt(5 ) - 1) = ( A ) ( 3 + sqrt(5) )/2 ( A ) ( 3 - sqrt(5) )/2 ( A ) ( 3 + sqrt(5) )/4 ( A ) ( 3 - sqrt(5) )/4

Evaluate : Find the value of sqrt( 3 + sqrt(5)) a ) sqrt(3)/2 + 1/sqrt(2) b ) sqrt(3)/2 - 1/2 c ) sqrt(5)/2 - 1/sqrt(2) d ) sqrt(5)/sqrt(2) + 1/sqrt(2)
