Evaluate :
`( 5 + sqrt7 ) ( 2 + sqrt5 ) - ( 5 + sqrt7 )^2`

Evaluate : ( sqrt(5) + sqrt(7 ) ) /( sqrt(5) - sqrt(7 ) )

Evaluate : ( sqrt(7) + sqrt(5) ) ( sqrt(5) - sqrt(7) )

Evaluate : sqrt(5)/ (sqrt(7) - sqrt(5)

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

Evaluate : (1+sqrt7)^5+(1-sqrt7)^5

sqrt7 - 3/5 sqrt7 + 2sqrt7

The value of (7sqrt2 +5) (7 sqrt2-5) is

The value of frac (7+3sqrt 5)(3 + sqrt 5)+frac(7 - 3sqrt 5)(3 - sqrt 5) lies between: frac (7 + 3 sqrt 5) (3 + sqrt 5) + frac (7 - 3 sqrt 5) (3 - sqrt 5) का मान के बीच है:

Evaluate (sqrt(7)-sqrt(5))/ (sqrt(7)-sqrt(5))
