Question

if (1 2 3)*A=(4 5) what is the order of matrix A

Answer 1

Let the order of the matrix be m x n

Order of (1 2 3) is 1 x 3

So, m must be 3 for their multiplication

As the resultant matrix has order 1 x 2

n must be 2

so, (1 x 3) (3 x 2) = (1 x 2)

So, order of Matrix A is 3 x 2

Answer 2

Answer:

the answer is 3 by 2 matrix
