1,3,6
1,2,4
4,5,6
2,4,6
If a ≠ b ≠ c, the value of x which satisfies the equation is.
x = 0
x = a
x = b
x = c
The inverse of is ___________.
Does not exist
and I is the unit matrix of order 2, then A2 equals
4 A - 3 I
3 A - 4 I
A- I
A + I
If A is a symmetric matrix and n ∈N, then An is
symmetric matrix
a diagonal matrix
skew symmetric matrix
none of these
If A is an invertible matrix of order n, then the determinant of adj (A) is equal to
|A|n
|A|n+1
|A|n-1
|A|n+2
, then |AB| =
80
100
-110
92
, then UV +XY =
