माना $A =\left(\begin{array}{lll}1 & 0 & 0 \\ 0 & 1 & 1 \\ 1 & 0 & 0\end{array}\right)$ है। तो $A ^{2025}- A ^{2020}$ बराबर है –

यदि$A = \left[ {\begin{array}{*{20}{c}}2&5\\3&7\end{array}} \right]$and $B = \left[ {\begin{array}{*{20}{c}}0&3\\4&1\end{array}} \right],$ तब

यादि  $A = [1\,\,2\,{\rm{ }}3]$ ओर $B = \left[ {\begin{array}{*{20}{c}}{ – 5}&4&0\\0&2&{ – 1}\\1&{ – 3}&2\end{array}} \right]$, तो $AB = $

$A =\left[a_{i j}\right]_{m \times n !}$ एक वर्ग आव्यूह है यदि

यदि $\left[ {\begin{array}{*{20}{c}}1&{\,\,1}&{\,\,1}\\1&{ – 2}&{ – 2}\\1&{\,\,3}&{\,\,1}\end{array}} \right]\,\left[ \begin{array}{l}x\\y\\z\end{array} \right] = \left[ \begin{array}{l}0\\3\\4\end{array} \right]$, तो $\left[ \begin{array}{l}x\\y\\z\end{array} \right]$=
