Rationalize :
`( 7 + sqrt3 ) / ( 7 - sqrt3 )`

Rationalize 3/(2sqrt7+sqrt5)

(3 + sqrt7)(3 - sqrt7)

Examine whether of the following numbers are rational or irrational . (i) 3 + sqrt(3)" " (ii) sqrt(7)-2 " " (iii)""^(3)sqrt(5) xx ""^(3)sqrt(25) sqrt(7) xx sqrt(343)" " (v)sqrt((13)/(117))" " (vi)sqrt(8) xx sqrt(2)

sqrt(3)(sqrt(7)-sqrt(3))

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

(sqrt7-sqrt3)^2

Examine,whether the following numbers are rational or irrational: sqrt(7) (ii) sqrt(4) (iii) 2+sqrt(3)

Rationalize the denominator: 4/(sqrt7+sqrt3)

(7+3sqrt5)/(7-3sqrt5)=

sqrt(7+4sqrt3) - sqrt(7-4sqrt3) =
