Each of the following statements is either true or false. Determine for each one whether it is true or false, if it is true prove it and if it is false disprove it (that is, prove its negation). f. Let a be a 3-digit integer. Then 3 divides a if and only if 3 divides the sum of the digits of a. g. For every integer n, if 12|n² then 12|n.
