Write in simplied form
( a ) `sqrt(6)`
( b ) `sqrt(7)`
( c ) `sqrt(8)`

The simplified form of ( 2)/(sqrt(7) + sqrt(5)) + (7)/(sqrt(12)- sqrt(5)) - (5)/(sqrt(12) - sqrt(7)) is

Simplify (a) (sqrt(8)-sqrt(6))^2 (b) (sqrt(5)-sqrt(8))^2

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

Identify the following types of surds : (a) sqrt(6)+5sqrt(3)" "(b)sqrt(15)+sqrt(8)-sqrt(11) " "(c)sqrt(5)" "(d) 5+sqrt(7)

Evaluate : ( sqrt(7) + sqrt(2) ) times ( sqrt(3) + sqrt(8) )

Evaluate : ( sqrt(7) - 6 ) times ( sqrt(3) - sqrt(7) )

If sqrt(6)-sqrt(7) the conjugate of sqrt(6)+sqrt(7)

Which of the following is irrational? (a) (2-sqrt3)2 (b) (sqrt2+sqrt3)2 (c) (sqrt2-sqrt3)(sqrt2+sqrt3) (d) (2sqrt7)/7
