We have represented numbers in base-2 (binary) and in base-16 (hex). We are now ready for unsigned base-4, which we call quad numbers. A quad digit can be 0, 1, 2, or 3 a. What is the maximum unsigned decimal value that one can represent with 3 quad digits? What is the maximum unsigned decimal value that one can represent with n quad digits (Hint: your answer should be a function of n)? Add the two unsigned quad numbers: 023 and 221? What is the quad representation of decimal number 42? b. c. d
