1. -29
Binary Format of 29: 11101
16 bit binary representation of 29 is 00000000 00011101
16 bit signed magnitude representation of -29 is 10000000 00011101
2’s complement form of -29 is NOT (00000000 00011101) +1
NOT (00000000 00011101) is 11111111 11100010
11111111 11100010 +1
11111111 11100011

2’s complement form of -29 is 11111111 11100011

2. 0 01111110 10100000000000000000000

Sign bit: 0 i.e. positive number
Exponent: 01111110 i.e. 8 bit
Significand: 10100000000000000000000 i.e. 23 bit

X= (-1)s*(1+significand)*2(exponent-127)

S=0
Exponent value in decimal= (01111110)2 =126
Significand = 101

X= (-1)0*(1.101) *2(126-127) =1*(1.101)
X’Y + XYZ’ + Y’ + XZ (Y+Y’) = 1

Left Hand Side:
X’Y + XYZ’ + Y’ + XZ (Y+Y’)
X’Y + XYZ’ + Y’ + XZY+XZY’ //Distributive law//
X’Y + XYZ’ + XZY + Y’ +XZY’ //Commutative Law//
X’Y+XY (Z’+Z) +Y’+XZY’ //Distributive law//
X’Y+XY (1) +Y’+XZY’ //Inverse Law//
X’Y+XY+Y’ (1) +XZY’ //Identity Law//
X’Y+XY+Y’ (Z+Z’) +XZY’ //Inverse Law//
X’Y+XY+Y’Z+Y’Z’+XZY’ //Distributive law//
X’Y+XY+Y’Z+XZY’+Y’Z’ //Commutative Law//
Y (X’+X) +Y’Z (1+X) +Y’Z’ //Distributive law//
Y (1) +Y’Z (1+X) +Y’Z’ //Inverse Law//
Y+Y’Z (1) +Y’Z’ //Null Law//
Y+Y’Z+Y’Z’
Y+Y’ (Z+Z’) //Distributive law//
Y+Y’ (1) //Inverse Law//
(Y+Y’) //Inverse Law//
1
Output for Left Hand Side is 1 which is equals to Right Hand side value
Therefore Left hand side is equal to Right hand side
i.e. X’Y + XYZ’ + Y’ + XZ (Y+Y’) = 1 4. Assumptions
