1. The problem statement, all variables and given/known data This really isn't a calc question so forgive me. Determine which base(radix) is used in the following operation : a ) 1234 + 1234 + 1234 + 1234 = 11101 b ) 19 * 18 = 297 I know the answer to a but am not sure how to get it. What I see is the for a) the answer has to be greater than base 4, and for b) it has to be radix >=10. Is there some tricks that could help me figure out what base is in general a expression is on?
