A= 3 -2 1 4 B= 0 -1 3 2 what is AB?
A 3 -3 4 6
B -6 -7 12 7
C -1 -4 11 2
D 0 2 3 8
To find AB, we need to multiply each element of matrix A by its corresponding element in matrix B and then sum the products.
Multiplying the first elements:
3 * 0 = 0
Multiplying the second elements:
-2 * -1 = 2
Multiplying the third elements:
1 * 3 = 3
Multiplying the fourth elements:
4 * 2 = 8
Putting these products together, we have:
AB = 0 2 3 8
So, the correct answer is D) 0 2 3 8
