I want to make sure I'm doing this problem right. Explanation is greatly appreciated

For this problem, there are 4 variables. x 3 is the most significant bit (leftmost) and x 0 is the least significant (rightmost). This means that m 12 is x 3 x 2 x 1 x 0 .

Select the equation that represents the simplest SOP form of ( m 0 , m 5 , m 7 , m 8 , m 10 , m 11 , m 14 ). Again simplest SOP!

Options:

x2x0+x1x0

(x3+x1+x0)(x2+x1+x0)(x2+x1+x0)(x3+x2+x0)

(x2+x0(x3+x1)(x2+x0)

x2x1x0+x3x2x0+x3x2x1x0+x3x2x1
