Simplify :
`sqrt(2) + 7 sqrt(2)`

Simplify : ((2 sqrt(45) + 3 sqrt(20)))/(2sqrt5)

Simplify : sqrt(192) - 1/2 sqrt(48) - sqrt(75) .

Simplify : 2sqrt(2)-3sqrt(32)+2sqrt(48)

Simplify: (i) (2 sqrt(2) + 3 sqrt(3)) (2 sqrt(2) - 3 sqrt(3)) (ii) (2 sqrt(8) - 3 sqrt(2))^(2) (iii) (sqrt(7) + sqrt(6))^(2) (iv) (6 - sqrt(2))(2 + sqrt(3))

Simplify : 4sqrt(2)-2sqrt(8)+(3)/(sqrt(2))

Simplify : (1)/(sqrt(3)+sqrt(2))-(1)/(sqrt(3)-sqrt(2))+(2)/(sqrt(2)+1)

Simplify: (sqrt(5)-2)/(sqrt(5)+2)-(sqrt(5)+2)/(sqrt(5)-2)

Simplify : (sqrt(5)+sqrt(2))^(2) (ii) (sqrt(11)-sqrt(5))^(2)

Simplify (sqrt(3)+sqrt(2))(sqrt(2)-sqrt(3))
