In Exercises 1–6, determine whether or not the given pairs of matrices are inverse pairs. [**HinT:** See Quick Examples 1–3.]

To determine

Whether the matrices

**Given Information:**

The provided matrices are

Consider the matrices

A matrix with *m* rows and *n* columns is of dimension *m* and *n* are positive integers.

Since, number of rows in

Substitute *m* and *n* in

Thus, dimension of

Since, number of rows in

Substitute *m* and *n* in

Thus, dimension of

Now, two matrices *A* and *B* are inverse pairs if *I* is the
