gunakan determinan dengan metode sarrus a = ( 4, 6, 0) b = (0, 0, 2) c = (-2,-3,1)

4....6....0...4...6
0....0....2...0...0
-2..-3....1..-2..-3

p = (4.x 0x 1) + (6.x2x.-2) +(0x.0x.3)
p= 0 - 24 +0
p = -24

q = (-2x0x0) + (-3x2x4) + (1x0x6)
q = 0 - 24 +0
q = -24

det = p - q
det = -24 - (-24)
det =0
