Question 10 9 pts For this problem, there are 4 variables. X3 is the most significant bit (leftmost) and Xo is the least significant (rightmost). This means that m12, is 23 22 21 20. Elements that are don't cares are written as dindex . For example, d12 would mean that we don't care what the output is when x3 = 1, X2 = 1,41 = 0, and xo = 0. Select the equation that represents the simplest POS form of 2 (do, m2, d5, d7, m8, d10, 013) . Again simplest POS! O (21 + xo) * (x2 + x1 + To ) * (72 + +1) T2+1 +2322 (x3 + x2 + 20 ) * (72 + +1) * (T3 + x2 + To) O (21 + x3 ) * (Q1 + x3) X2 . To o (x2 + To ) * (72 + )
