Math Problem Statement
Solution
We are tasked with solving the expression:
We are provided with the inverses of the matrices , , and , but we do not need to find , , or explicitly. Instead, we'll use matrix properties and inverses to simplify the expression.
Step-by-Step Approach:
-
Rewrite the Expression:
Using matrix properties:
This simplifies the expression to:
= \left( \frac{1}{2} A^2 C B^T \right)^{-1}$$ -
Apply the Inverse:
The inverse of a product of matrices , so applying the inverse:
-
Simplify Further:
- (since the inverse of a transpose is the transpose of the inverse),
- (since the inverse of is the square of ).
Thus, the expression becomes:
Conclusion:
The final simplified expression is:
You can now substitute the given values of , , and to compute the final result.
