Explanation Given: The value of A and B is given as A = [ 0 0 5 0 0 − 3 0 0 4 ] B = [ 6 − 11 4 8 16 4 0 0 0 ] Approach: Consider the two matrices A and B as follows. A = [ a 11 a 12 ⋯ a 1 n a 21 a 22 ⋯ a 2 n ⋮ ⋮ ⋱ ⋮ a m 1 a m 2 a m 3 a m n ] m × n B = [ b 11 b 12 ⋯ b 1 l b 21 b 22 ⋯ b 2 l ⋮ ⋮ ⋱ ⋮ b k 1 b k 2 b k 3 b k l ] k × l Multiplication of A and B is possible only if n = k (that is the number of columns of first matrix A should be equal to the number of rows of matrix B in multiplication.) and the dimension of A B would be m × l . Multiplication of A and B is A B = [ a 11 ⋅ b 11 + a 12 ⋅ b 21 + ... + a 1 n ⋅ b k 1 a 11 ⋅ b 12 + a 12 ⋅ b 22 + ... + a 1 n ⋅ b k 2 ⋯ a 11 ⋅ b 1 l + a 12 ⋅ b 2 l + ... + a 1 n ⋅ b k l a 21 ⋅ b 11 + a 22 ⋅ b 21 + ... + a 2 n ⋅ b k 1 a 21 ⋅ b 12 + a 22 ⋅ b 22 + ... + a 2 n ⋅ b k 2 ⋯ a 21 ⋅ b 1 l + a 22 ⋅ b 2 l + ... + a 2 n ⋅ b k l ⋮ ⋮ ⋱ ⋮ a m 1 ⋅ b 11 + a m 2 ⋅ b 21 +
