\((AB)^{-1} = B^{-1}A^{-1}\)
\((AB)^{-1} = A^{-1}B^{-1}\)
\((AB)^{-1} = A^{-1}B\)
\((AB)^{-1} = AB^{-1}\)
Hide Solution
Verified By Collegedunia
The Correct Option is
A
Solution and Explanation
The inverse of the product of two invertible matrices follows the rule: \[ (AB)^{-1} = B^{-1}A^{-1}. \] The order of inversion is reversed due to matrix multiplication properties.

Assertion (A): If $| \mathbf{a} \times \mathbf{b} |^2 + | \mathbf{a} \cdot \mathbf{b} |^2 = 256$ and $| \mathbf{b} | = 8$, then $| \mathbf{a} | = 2$.
Reason (R): $\sin^2 \theta + \cos^2 \theta = 1$ and $| \mathbf{a} \times \mathbf{b} | = | \mathbf{a} | | \mathbf{b} | \sin \theta$ and $ \mathbf{a} \cdot \mathbf{b} = | \mathbf{a} | | \mathbf{b} | \cos \theta$.
