Evaluate :
( a ) `( sqrt(7) + sqrt(3) )^2`
( b ) `( sqrt(9) - sqrt(5) )^2`

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

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

Evaluate : ( sqrt(2) - sqrt(3) + sqrt(5) )times ( sqrt(2) + sqrt(3) + sqrt(5) )

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

Evaluate : Find the value of sqrt( 3 + sqrt(5)) a ) sqrt(3)/2 + 1/sqrt(2) b ) sqrt(3)/2 - 1/2 c ) sqrt(5)/2 - 1/sqrt(2) d ) sqrt(5)/sqrt(2) + 1/sqrt(2)

(2sqrt(7))/(sqrt(5)-sqrt(3))

sqrt(9)/(sqrt(7)+sqrt(2))

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