If l, m and n are real numbers such that l2 + m2 + n2 = 0, then
is equal to
0
1
l + m + n + 2
2(l + m + n) + 3
, then
is one of the cube roots of unity
is one of the cube roots of unity
is one of the cube roots of unity
is one of the cube roots of unity
The output of the circuit is
(x2 + x3) . [(x1 · x2) . x3']
(x2 + x3') . [(x1 · x2) . x3']
(x2 + x3) + [(x1 · x2) . x3']
(x2 . x3) . [(x1 · x2) . x3']
If is equal to
C.
