Pandigital and Pretty Powerful V (Posted on 2023-04-20)

Determine all triplets (X, Y, Z) of base 12 positive integers such that the duodecimal representation of X^Y*(X+1)^Z has no leading zeroes and contains each of the digits from 0 to B exactly once, with the restriction that: at least one of Y and Z is different from 1.

What is the total number of such triplets without any restriction?

Solution: (Hide)

There are precisely two triplets given by:
(X,Y, Z) = (1BB, 4,1), (A084, 2,1),so that:
1BB^4 * 1BA^1 = 2740936815BA
and A084^2 * A085^1 = 70962B1345A8
