Evaluate :

`( 4 + sqrt5 )/ ( 4 - sqrt5 ) + ( 4 - sqrt5 ) / ( 4 + sqrt5 )`

Evaluate : sqrt( 4 ! )/sqrt( 5! ) = ? ( A ) 5/sqrt(5) ( B ) sqrt(5) /5

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

Evaluate log((8xx4 sqrt5)/81)

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

sqrt(5x -4)

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

Solve : ( 2 + sqrt5 ) times ( sqrt3 + 4 )

simplify :(4+sqrt(5))/(4-sqrt(5))+(4-sqrt(5))/(4+sqrt(5))

Simplify: (4+sqrt(5))/(4-sqrt(5))+(4-sqrt(5))/(4+sqrt(5))
