curriculum. Provide examples to support your answers. (20 marks) In your
assignment responses include the following: • What is indigenous knowledge.
• Why it is important to learn about indigenous knowledge in the curriculum?
To determine which statement among the options provided is false, we need
to analyze each statement based on the properties of matrix multiplication.
Let’s denote the matrices as follows:
A: a matrix of size m x n
B: a matrix of size p x q
C: a matrix of size r x s
Step-by-Step Analysis
1. Statement (a): The result of B C is
For the product 𝐵𝐶 to be defined, the number of columns in
matrix 𝐵 must equal the number of rows in matrix 𝐶. Therefore,
if 𝐵 is 𝑝×𝑞 and 𝐶 is 𝑟×𝑠, then this operation is valid only if 𝑞=𝑟. If
this condition holds true, then this statement can be considered
true.
2. Statement (b): The result of A C is
Similarly, for the product 𝐴𝐶 to be defined, the number of columns
in matrix 𝐴 must equal the number of rows in matrix 𝐶. Thus,
if 𝐴 is 𝑚×𝑛 and 𝐶 is 𝑟×𝑠, this operation will be valid if and only
if 𝑛=𝑟. If this condition holds true, then this statement can also be
considered true.
3. Statement (c): B C = C B
