To determine

The matrices are inverse of each other by showing that their product is the identity matrix

**Given:**

The two matrices are

**Approach:**

To check whether the given two matrices are inverses of each other or not, it is necessary to take product of these two matrices. If the product of these two matrices is an identity matrix then these two matrices are inverses of each other.

**Calculation:**

The product of given two matrices is,
