Step 1
We have to evaluate the determinant of each of the following matrices:
a. [10965]
b. [4358]
We know the value of determinant of matrix will be calculated in the following ways: [abcd]=|abcd|
=a×db×c
So calculating for part (a),
[10965]=|10965|
=10×59×6
=5054
=4
Hence, value of determinant is -4.
Step 2
calculating for part (b),
[4358]=|4358|
=4×(8)3×(5)
=32+15
=17
Hence, value of determinant is -17.
