Evaluate :

`(1/( 3 - sqrt8 )) - (1/(sqrt8 - sqrt7 ))`

(1/(3-sqrt(8))-1/(sqrt(8)-sqrt(7)))

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))) ?

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)

Solve: (1)/(sqrt(3)-8)-(1)/(sqrt(8)-sqrt(7))

Evaluate : 1/sqrt(2) times sqrt(8)

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