MCQ

The number of different possible orders of matrices having $18$ identical elements is:

A
$3$
B
$1$
✓
$6$
D
$4$

✓

Answer

Correct option: C.

$6$

Let the order of the matrix is $ (\text{a}\times\text{b})$ There are $18$ elements in the matrix.
So, $\text{a}\times\text{b} = 18$
Possible orders can be $ (1\times18),( 18\times1),( 2\times9),( 9\times2),( 3\times6),( 6\times3)$
There are $6$ possible orders.
