Hi,
He must have given more conditions like all the numbers are integers, none of them is equal to 1, all are single digit numbers, something like that. Because, based on your wording, there can be more than 1 solution.
E.g-1.) 2^6=4^3=8^2 = 64. So, xyz is 6.3.2 = 36
E.g-2.) 2^6=4^3=64^1 = 64. So, xyz is 6.3.1 = 18
E.g-3.) 2^6=8^2=64^1 = 64. So, xyz is 6.2.1 = 12
E.g-4.) 4^3=8^2=64^1 = 64. So, xyz is 3.2.1 = 6

Cheers!

Frankenstein showed different solutions.

If they gave no further constraints, my guess is that the question asked something like "which of the following numbers is possible for xyz".
