Evaluate :

`( sqrt(8 ) - sqrt5 ) / ( sqrt8 + sqrt5 ) + 4sqrt10`

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

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

(4-sqrt5)/sqrt10

Evaluate : sqrt(5) + sqrt(5) + sqrt(5) + sqrt (5)

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

Evaluate : sqrt( 5 + sqrt( 5 + sqrt ( 5 + sqrt( 5 ----- oo )))

Evaluate : sqrt( 5 + sqrt( 5 + sqrt ( 5 + sqrt( 5 ----- oo )))

The value of (1)/( sqrt(7) - sqrt(6)) - (1)/( sqrt(6) - sqrt(5) ) +(1)/( sqrt(5) -2) - (1)/( sqrt(8) - sqrt(7) ) +(1)/( 3- sqrt(8)) is

Evaluate : ((3) - sqrt(8)) / ((3) + sqrt(8) + ( (3) + sqrt(8)) / ( (3) - sqrt(8)

What is the value of (1/(sqrt(9) - sqrt(8)) - 1/(sqrt(8) - sqrt(7)) + 1/(sqrt(7) - sqrt(6)) - 1/(sqrt(6) - sqrt(5)) + 1/(sqrt(5) - sqrt(4))) ?
