Convert the binary expansion of each of these integers to a decimal expansion.a) (1 1011)2________________b) (10 1011 0101)2________________c) (11 1011 1110)2________________d) (1111 1100 0001 1111)2

SOLUTION Step 1 We have to convert the binary expansion of the following integers to decimal expansion.Step 21. = = 16 + 8 + 2 +1 = 27 Hence we write = Step 3 b) == 512 + 128 + 32 + 16+4+1= 693 Hence we write = Step 4c) == 512 + 256 + 128 + 32 + 16 + 8+ 4 +2 = 958 = Step 5 d) = = 64543 =
