(c) –17 is a negative integer and it can be (c)
represented in three ways. For this first we
will obtain 8-bit representation of +17
which is :
00010001
Representation of –17 in 3 ways is obtained:

1. Signed-magnitude : just complement sign MSB
bit:
10010001
2. Signed - 1's complement : Take 1's 1's 1's
complement including sign bit :
11101110
3. Signed- 2's complement : Take 2's 2's 2's
complement of complete number :
11101111
(d) – 63 can be represented using + 63 which (d)
is 00111111

1. Signed-magnitude → 10111111 gmBÝS>-_op½ZQ²>`yS>
2. Signed- 1's complement → 11000000 gmBÝS>- 1's H$m°påßb_|Q
3. Signed- 2's complement →11000001 gmBÝS>- 2's H$m°påßb_|Q
