If B is a non-singular matrix and A is a square matrix such that B-1AB exists, then det (B-1AB) is equal to
det(A-1)
det (B-1)
det(B)
det(A)
If 1, w, w2 are the cube roots of unity and if
, a2 + b2 is equal to
1 + w2
w2 - 1
1 + w
(1 + w)2
C.
1 + w
If the three linear equations
x + 4ay + az = 0
x + 3by + bz = 0
x + 2cy + cz = 0
have a non-trivial solution, where a, then ab + bc is equal to
2ac
- ac
ac
- 2ac
The boolean expression corresponding to the combinational circuit is
(x1 + x2 · x'3)x2
(x1 . (x2 + x3)) + x2
(x1 . (x2 + x'3)) + x2
(x1 + (x2 + x'3)) + x3
In a boolean algebra B with respect to '+' and '.', x' denotes the negation of x B. Then
x - x' = 1 and x · x' = 1
x + x' = 1 and x . x' = 0
x + x' = 0 and x . x' = 0
x + x' = 0 and x . x' = 0
