If 8 * 8 = 54, what is 9 * 9


I think the answer is 69. Because 8 times 8 equals 54 is correct, we can judge that 54 here should be equal to 64 in decimal system. Suppose it is n-ary system, then 5 * n + 4 = 64, find n = 12. While 9 times 9 in decimal system, the result is 81, converted into 12 decimal system is 69
