Need this answered asap plz. Thanks!

Part A: Understanding the relationship between hexadecimal, binary, and decimal representations are very important when discussing machine-level programs.

See the example below.

Weights	128	64	32	16	8	4	2	1
Base 2	27	26	25	24	23	22	21	20
Example	1	0	1	1	0	0	1	0

1*128 + 0*64+1*32+1*16+0*8+0*4+1*2+0*1 = 178

Weights	256	16	1
Base 16	162	161	160
Example	0	B	2

0*256 + 11*16 +2*1 = 178

A=10

B=11

C=12

D=13

E=14

F=15

Two's complement: The most significant bits of the word have a negative weight. To get the two's complement of a binary number, invert the digits, then add one to the result. See example below.

00001110 = 14

11110010 = -14

1) Convert the following hexadecimal number to binary and decimal: 5C.

2) Convert the following binary number to hexadecimal and decimal: 00001110.

3) Convert the following decimal number to hexadecimal and binary: 88.

4) Use two's complement to convert the following decimal number to binary: -49.
