Write true (T) or false (F) for the following statements: 392 is a perfect cube. 8640 is not a perfect cube. No cube can end with exactly two zeros. There is no perfect cube which ends in 4. For an integer a, `a^3` is always greater than `a^2dot` If `a\ a n d\ b` are integers such that `a^2> b^2, t h e n\ a^3> b^3dot` If `a` divides `b` , then `a^3` divides `b^3dot` If `a^2` ends in 9, then `a^3` ends in 7 If `a^2` ends in 5, then `a^3` ends in 25. If `a^2` ends in an even number of zeros, then ends in and odd number zeros.
