1. The problem statement, all variables and given/known data
1) Let $$D_n-1 D_n-2...D_0$$ be a n-digit unsigned number with base(radix)=b. How much is it in decimal?

2) How can you convert $$301_10$$ to a number with base b?

3) What is the range of n-digit unsigned integers with base=b?

2. Relevant equations

3. The attempt at a solution
$$D_(n-1) * b^0 + D_(n-2) * b^1 + ... D_(0) * b^?$$

I'm not even sure that's right...
