Evaluate :
`sqrt(8) - sqrt(x) = sqrt(x) - sqrt(4)`

Evaluate : sqrt(( 1 - sqrt(x)) / ( 1 + sqrt(x) )

Evaluate : ( sqrt(8) - sqrt(2) ) times ( sqrt(8) + sqrt(2) )

Evaluate : int(sqrt(x+1)-sqrt(x-1))/(sqrt(x+1)+sqrt(x-1))dx

Evaluate : sqrt( x^3 sqrt ( x^3 sqrt ( x^3 ) ))

Evaluate: int sqrt((1-sqrt(x))/(1+sqrt(x)))

Find x : ( sqrt(x) + sqrt(a) ) / ( sqrt(x) - sqrt(a) ) + ( sqrt(x) - sqrt(a) ) / ( sqrt(x) + sqrt(a) ) = 6

Evaluate (sqrt(x)+sqrt(y))(sqrt(x)-sqrt(y))

(sqrt(x)+sqrt(3))^(4)+(sqrt(x)-sqrt(3))^(4)

Evaluate ((x+sqrt(3))(x-sqrt(5))+(x+sqrt(5))(x-sqrt(3)))/((x-sqrt(3))(x-sqrt(5)))
