since 0 is also divisible by 10, can we not have x = 0?

Couldn't x = 10 (10 is divisible by 10)? If so, the hundreds digit would be 1 (10^10 = 100). Any insight would be helpful...

X can be any positive multiple of 10 so yes if x=10 then the expression will be 10^10 and hundred digit will be 0 because 10^10= 10*10*10*10*10...10 times= 10000000000

Consider x=20,even then Hundreds digit will be 0

We are given that x is a positive integer, so x cannot be 0. 0 is neither positive nor negative integer.

As for 0^0: 0^0, in some sources equals to 1, some mathematicians say it's undefined. But you won't need this for the GMAT because the case of 0^0 is not tested on the GMAT.
