Answer:
The general relationship between each pair in terms of decimal values, powers of 2 and number of bit required are shown in form of table below:
Binary No. Decimal Value Power of 2 No. of Bits(n) Relation Ship
a=00011111 31 2⁵-1 n=5 b=a+1
b=00100000 32 2⁵ n+1=6
a=00111111 63 2⁶-1 n=6 b=a+1
b=01000000 64 2⁶ n=6+1
a=01111111 127 2⁷-1 n=7 b=a+1
b=10000000 128 2⁷ n+1=8
