3 Converting binary (base 2 ) to hexadecimal (base 16) (8+6 points) Consider the example below: Let 11010101 be the binary representation of a number. When converted to decimal, we obtain the number as base2dec (11010101,2)=213. When converted to hexadecimal representation, we obtain the number as dec2base (213,16)= D5. We note that the last digit of hexadecimal representation (5) is the decimal representation of last 4 digits of binary representation (0101), that is basezdec (0101,,2)=5, and the second last digit of the hexadecimal representation (D) is the decimal representation of first 4 digits in binary representation (1101), that is base2dec ("1101", 2) =13 which is "D" in hexadecimal. a) Prove that the following statement is ALWAYS true (note that your proof must be done for general conditions and not using the specific example): - "If abode fgh2 is the binary representation of a number with 8 digits (which can either be 0 or 1 ). then the hexadecimal representation of the number is given by xy16 with 2 digits where x is the decimal equivalent of the first 4 binary digits "abod" and y is the decimal equivalent of the last. four binary digits "efgh"," b) Using the statement above, make following conversions in one step (withoit using bavie2dec or dec2base commands): - Convert 11100110 froan binary to hexadecimal - Convert 00100111 from binary to hexadecimal. - Convert E2 from hexidecimal to binary
