a) -13 b) -110 c) 38 d) none of the above
Im not sure on how to do this question. What I have done so far is convert the hexadecimal number into a decimal, but since it's already in 2's complement, how do I know the sign?

There's a computer science stack exchange. Your question might suit that site better. – badjohn Apr 12 '18 at 21:51

Since the leading bit is $0$ the number is positive. You don't have to worry about the $2$s complement, just convert it to decimal. $5\cdot 16+6=86$
