Consider the set A of all determinants of order 3 with entries 0 or 1 only. Let B be the subset of A consisting of all determinants with value 1. Let C be the subset of A consisting of all determinants with value –1. Then
C is empty
B has as many elements as C
A = B ( C
B has twice as many elements as elements as C
If A and B are square matrices of equal degree, then which one is correct among the following?
A +B =B+A
A+B =A+B
A-B =B-A
AB =BA
The parameter, on which the value of the determinant
does not depend upon is
a
p
d
