[(3+2sqrt(2))^(-2)+(3-2sqrt(2))^(-2)],[[" (a) "198," (b) "180]]

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

(2sqrt3 + sqrt2)(2sqrt3-sqrt2)

(3 + sqrt2)(2-sqrt3)(3-sqrt2)(2+sqrt3)

(2sqrt(3)+3sqrt(2))/(3sqrt(2)-2sqrt(3))

(sqrt3/2)^2-(sqrt3)^2+(sqrt2)^2+1/2

(sqrt(7)+2sqrt(3))(sqrt(7)-2sqrt(3))

1/(sqrt(9)-\ sqrt(8)) is equal to: (a) 3+2sqrt(2) (b) 1/(3+2sqrt(2)) (c) 3-2sqrt(2) (d) 3/2-\ sqrt(2)

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 ((sqrt(3))/(2))^(2)-(sqrt(3))^(2)+(sqrt(2))^(2)+(1)/(2)
