A square matrix P satisfies \(P^2 = I - P\). If \(P^n = 5I - 8P\) then n is equal to
If \( A = \begin{pmatrix} 1 & -2 4 & 5 \end{pmatrix} \); \( f(t) = t^2 - 3t + 7 \) then \( f(A) + \begin{pmatrix 3 & 6 -12 & -9 \end{pmatrix} = \)}
If matrix A = [ 2 -2 ] [ -2 2 ] and A² = pA, then the value of p is:
If $A = \begin{bmatrix}1&0\\ 1&1\end{bmatrix}$ and $A^8 = aA +bI,$ then $(a , b) = $
If $A = \begin{bmatrix}a&0&0\\ 0&a&0\\ 0&0&a\end{bmatrix}$, then det(adj A) is
If $A= \begin{bmatrix}1&2\\ 0&1\end{bmatrix} $, then $A^n$ is
If $n$ is a non-negative integer and $A = \begin{bmatrix}1&0\\ 1&1\end{bmatrix} $ , then $A^n = $
If $A$ is a square matrix.such that $A^3 = 0$, then $(I + A)^{-1}$ is
