I have a homework problem and I don't understand it. Here is the problem: The base two number 11111(base 2) has the same digit in all places. The same number can be written in different bases. Find two other bases where the number has the same digit in all it's places.
I get that 11111 base 2 = 31, but I don't really understand what the question is asking me or how to "solve" it.
