(root(6)(5))(root(3)(2))(sqrt(3))(root(12)(6)) =

root(3)(4) times root(6)(5)

(i) Simplify (2^(2/3)-2^((-2)/3))(2^(4/3)+1+2^((-4)/3)) (ii) [(root(6)(7))^(2)+(root(6)(7))^(-2)][(root(6)(7))^(4)-1+(root(6)(7))^(-4)]

root(3)((x-4)(x-6))>2

Evaluate: (6^(2/3) xx root(3)((6)^(7)))/(root(3)(6^(6)))

Simplify [root(3)(root(6)(2^(9)))]^(4)xx[root(6)(root(3)(2^(9)))]^(4) .
