Pragati Sharma answered |
Introduction:
In this problem, we are given a 3x3 matrix A with integer entries and we need to find the maximum possible number of entries of A that are even, given that det(A) = 1.
Solution:
To find the maximum number of even entries in A, we need to consider the following cases:
Case 1: No even entries in A
If there are no even entries in... more
