(11+)[2sqrt(54)-6sqrt(2)/3-sqrt(96)]" is equat to "

(2sqrt(6))/(sqrt(2)+sqrt(3)+sqrt(5)) equals

Let z_(1)=(2sqrt(3)+ i6sqrt(7))/(6sqrt(7)+ i2sqrt(3))" and "z_(2)=(sqrt(11)+ i3sqrt(13))/(3sqrt(13)- isqrt(11)) . Then |(1)/(z_1)+(1)/(z_2)| is equal to

Factorize 6+2sqrt(3)-sqrt(8)-2sqrt(6)

2sqrt(6)xx3sqrt(54) = :-

The value of sqrt(9-2sqrt(11-6sqrt(2))) is closest to :

(3-sqrt(6))/(3+2sqrt(6))=a sqrt(6)-b
