For scalar multiplication, if k is a scalar and A and B are matrices of the same order, then k(A + B) equals:
For scalar multiplication, if k is a scalar and A and B are matrices of the same order, then k(A + B) equals:
- A. kA + B
- B. A + kB
- C. k(AB)
- D. kA + kB
Answer: D) kA + kB
Explanation: Scalar multiplication distributes over matrix addition. Thus, k(A + B) = kA + kB.
