Is the answer "Two"?

Only possible two digits with the defined length as 6 are 2*2*2*2*2*2 = 64 and 2*2*2*2*2*3 = 96.

I also feel that it should be 2 only as stated 64 & 96. I started replacing from the end and tried to see if I can make some more numbers. But could not.

Would go for Two.

Btw, 1 is not a prime number because, it is only divisible by 1 and all primes should be divisible by 1 and the same numbers themselves.

Two is answer.

2^6 = 64 and 2^5*3 = 96 are the two digitive positive numbers.
