MCQ
If a matrix P has 8 elements then how many different values the order of the matrix can take?
  • A
    3
  • ✓
    4
  • C
    8
  • D
    6
✓

Answer

Correct option: B.
4
A matrix of mm rows and n columns has m × n elements.
8 can be got by all combinations of 1 × 8, 8 × 1, 2 × 4, 4 × 2

Hence, there are 4 possible matrices which have 8 elements.
