Question

What is the highest decimal number that can be represented by each of the following numbers of binary digits (bits)? (a) two (b) three (c) four (d) five (e) six (f) seven (g) eight

Answer 1

Answer:

1 of 11

(a) \ If number of bits= n n

Then highest decimal number represented by n n bits =

\color{#4257b2}2^n-1 2n−1

Number of bits= 22

Then highest decimal number by 22 bits =

2^2-122−1=\color{#4257b2}3

3

So B would be the answer
