Question

If the order of two matrices A and B are 2×4 and 3×2 respectively then the order of AB is​

Answer 1

Answer:

No answer because the product AB does not exist!

The order of BA though is 3x4.

Step-by-step explanation:

The product CD of two matrices is defined only when the number of columns in C and equal to the number of rows in D.  The result has as many rows as C and as many columns as D.

A has 4 columns.  B has 3 rows.  So AB is not defined.

B has 2 columns.  A has 2 rows.  So BA is defined.  It has 3 rows like B and 4 columns like A.
