In the group G = {1, 3, 7, 9} under multiplication modulo 10, the inverse of 3 is
1
3
7
9
C.
7
Given, G = {1, 3, 7, 9}
Here,
It is clearthat 1 is the identity element.
Since, G is a group, then inverse of each element exist in G.
If O(A) = 2 x 3, O(B) = 3 x 2, and O(C) = 3 x 3, which one ofthe following is not defined?
CB + A'
BAC
C(A + B')'
C(A + B')
If A = is singular, then the possible values of x are
0, 12, - 12
0, 1, - 1
0, 4, - 4
0, 5, - 5
The value of is
x(x - p)(x - q)
(x - p)(x - q)(x + p + q)
(p - q)(x - q)(x - p)
pq(x - p)(x - q)
