2sqrt(10)times sqrt(15)=?

((1)/(sqrt(2))+(3)/(sqrt(2)))times sqrt(2)=?

sqrt(10)xx sqrt(15)

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

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

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

(sqrt(2)+sqrt(3))times(sqrt(3)+sqrt(8))

2sqrt10 times sqrt3 times 2sqrt2 is equal to___

sqrt(10+2sqrt(6)+2sqrt(10)+2sqrt(15)) is equal to (sqrt(2)+sqrt(3)+sqrt(5))(sqrt(2)+sqrt(3)-sqrt(5))(c)(sqrt(2)+sqrt(5)-sqrt(3))(d) None of these

(i) 3sqrt(5) by 2sqrt(5) ,(ii) 6sqrt(15) by 4sqrt(3) , (iii) 2sqrt(6) by 3sqrt(3) (iv) 3sqrt(8) by 3sqrt(2) ,(v) sqrt(10) by sqrt(40) , (vi) 3sqrt(28) by 2sqrt(7)
