Can you help me with these three problems thank you
![### Inverse of Matrices
Understanding how to operate with inverses of matrices is a crucial concept in linear algebra. The following problems focus on finding the inverses of given matrices and matrix products.
#### Problems:
**h)** \( B^{-1} = \)
**i)** \( (BD)^{-1} = \)
**j)** \( (DC)^{-1} = \)
#### Instructions:
For each of these problems, you are required to find the inverse of the given matrix or inverse of the product of matrices. Here’s a brief guideline on how to approach these problems:
1. **Single Matrix Inverse (Problem h)**:
- A matrix \(B\) is given. Use the inverse formula or properties of the matrix to find \( B^{-1} \).
2. **Product of Matrices Inverse (Problems i and j)**:
- For the product of two matrices such as \( (BD)^{-1} \) and \( (DC)^{-1} \), recall that the inverse of a product of matrices is the product of the inverses in reverse order:
\[
(BD)^{-1} = D^{-1}B^{-1}
\]
\[
(DC)^{-1} = C^{-1}D^{-1}
\]
Go through each problem systematically, making sure to apply the correct matrix algebra principles to find the inverses. If any specific properties or conditions of the matrices are given (e.g., if they are diagonal, orthogonal, etc.), use those to your advantage in simplifying the work.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff39d4e73-8442-4223-8525-8f555980c50a%2F4e7ffb09-b599-49f0-804b-71136efe73c3%2F6x7anq_processed.jpeg&w=3840&q=75)
