Problem
Let the product 
, each factor written in base 
, equals 
in base . Let 
, each term expressed in base . Then 
, in base , is
Solution
Converting everything into base 
, we have 
. Looking ahead, the constant term of the polynomial will be 
. By the Rational Root Theorem, the only possible integer roots are 
. Bases 
do not have a 
as a digit. Testing 
gives a solution that works.
Therefore, we are working in base 
. Adding the units place in base , 
, so we carry the 
to get a total of 
, which is option 
.
