Largest 3 digit number in base 6 will be 215 (of base 10) (right?)
I don't know its form in base 6 but its not needed
largest 3 digit perfect square less than that is 196.. This is to be represented in a new number system in two digits
So it should be less than the square of the number
Next greatest number is 15. So x = 15
x in base 7 is 20

So i guess it should be even but not perfect square
