Answer :
Answer:
-80
Explanation:
We have: 1 0 1 1 0 0 0 0
Then we assign to each digit the corresponding power of 2.
See it in a table:
[tex]\begin{matrix}1&0&1&1&0&0&0&0\\2^7&2^6&2^5&2^4&2^3&2^2&2^1&2^0 \end{matrix}[/tex]
Then multiplying each digit by its corresponding power of 2 and then adding the results, we get:
[tex]-2^7+2^5+2^4[/tex]
Notice the very first digit to the left corresponding to the [tex]2^7[/tex] power should be negative according to the format of two’s complement representation.
We get:
[tex]-128+32+16=-80[/tex]
