Determining Zero Equivalence

[New] Problem :simplify .

>> sqrt(997)-(997^3)^(1/6);

                                     1/6      1/2
                          - 991026973    + 997   

>> simplify(%);

                                     0

[New] Problem :simplify .

>> sqrt(999983)-(999983^3)^(1/6);

                           1/2                     1/6
                     999983    - 999949000866995087   

>> simplify(%);

                                     0

[New] Problem : recognize that is 0.

>> simplify(expand((2^(1/3)+4^(1/3))^3-6*(2^(1/3)+4^(1/3))-6));

                                     0
