64= 2x2x2x2x2x2 so its length is equal to 6
96= 2x2x2x2x2x3 so its length is equal to 6
The last try to find another two digit number-with length equals to 6 is to substitute the last 2 of the number 96 with 3, the result is:
2x2x2x2x3x3= 144 that's a three-digit number. Therefore, the answer is TWO.
