Chapter 4.3, Problem 1ACYP

To determine

To find:Whether the given product is defined or not.

Answer to Problem 1ACYP

The product is defined and the dimension of product is $4\times 2$ .

Explanation of Solution

Given information:

The productis $A_{4\times 6}\cdot B_{6\times 2}$ .

Calculation:

Consider the product.

  $A_{4\times 6}\cdot B_{6\times 2}$

Since, the inner dimensions of both the matrices are equal.

Thus, the product is defined and the dimension of product is $4\times 2$ .
