2’s complement system: You are given four signed integers indifferent number bases
A = +(7B)16 B = -(21)8 C = +(153)10 D = +(1111001)2
a) What is the value n, the smallest number of bits needed torepresent all of these numbers in 2’s complement representation? Ingeneral, using the value found for n, what is the total range ofnumbers that can be represented?
b) Give the n-bit representations of the four numbers in the 2’scomplement system, where n is the value determined in (a).
c) Compute using C + D. Is this the answer you would expect? Ifnot, what change would be needed to allow
