We call n = a 2 + 3 b 2 as the good representation of n . For example, 7 is a good integer. 7 = 2 2 + 3 × 1 2 is its good representation. Which of the following holds true? OPTIONS     1) If n 1 and n 2 are good, then n 1 × n 2 is good.   2) Every good integer has a unique good representation.   3) All odd good integers have unique good representations.   4) All even good integers have unique good representations.   5) More than one of the above is true discuss | yesterday's solution | more questions Tip of the Day At times, in a reading comprehension question,
