if the base 8 representation of a perfect square is ab3c, where a is not 0, then b is? steps too please... i only know c is 0, 1, or 4..
(it's solvable, so don't say "not enough info!" or stuff like that, thanks)

actually, unlike other yahoo users who copy their homework questions onto this site,
1) this isn't homework, i'm self - studying
2) i've been working on this question for a straight 45 minutes already.
so, don't hate. really.

Quoting from the following website

A perfect square can be 0,1,4, or 9 modulo 16 (verify!), which means that it can be 0, 1, 4, 9, 16, 17, 20, 25, 32, 33, 36, 41, 48, 49, 52, 57 modulo 64. (There are actually less than this, but I didn't want to check 64 numbers ) This gives us the last two digits base 8. Of these, the only one with an "eights" digit of 3 is 25, which converts to . The answer is 1.
25. If the base 8 representation of a perfect square is ab3c, where a is not 0, then c is:
A) 0
B) 1
C) 3
D) 4
E) Not uniquely determined

Why rephrase it when brilliant minds before have already done so?

I'd love to help but apparently I'm not smart enough to solve this math problem. If I do, I wouldn't be here. I'd be in calculus class. But unfortunately, I dropped out.

A: 1
B: 9
C: 6

Show my work? Trial and error, thank you. Other solutions include:
3136 (56^2)
8836 (94^2)

It is obvious that people like you who ask problems like this only want help with their homework: if u have trouble with homework then ask SOMEONE FOR GOD'S sake! if not then u r VERY lazy!
