Represent the number 8 in two's complement in base two on four bits. Illustrate the various steps and any problems. Then convert it to base 16 (always in two's complement). 3 Add the two 8-bit numbers in two's complement (base 16) A3 and 7F. Illustrate the various steps and any problems. 4 Having 6 bits a vailable, indicate, both in binary and in decimal, the largest and smallest admissible value for representation in CA2 and pure binary. 5 The following hexadecimal numbers represent binary numbers encoded in CA2 over 8 bits . Record these numbers in order ascending of value. (It is not necessary to write the corr esponding decimal value). 01A2B232807EFE 6 Indicate the value of the hexadecimal number B5 considering it in: 1. pure binary 2. form and sign 3. two's complement
