Answer:
10
Explanation:
Adding two binary numbers 0111 and 1001 results in the sum as 10000.
The equivalent hex representation for the number is obtained by splitting the result into two quads and finding their individual hex representations.
00010000
Quad 1 : 0001 = 1 (HEX)
Quad 2 : 0000 = 0 (HEX)
So the equivalent result is obtained by concatenating the two digits one after the other : 10 (in Hex)
