JEE Main 202116 Mar, Morning shiftMathematicsHardMatrices and Determinants245× since 2002Let A=[i−i−ii],i=−1A = \left[ {\matrix{ i & { - i} \cr { - i} & i \cr } } \right],i = \sqrt { - 1}A=[i−i−ii],i=−1. Then, the system of linear equations A8[xy]=[864]{A^8}\left[ {\matrix{ x \cr y \cr } } \right] = \left[ {\matrix{ 8 \cr {64} \cr } } \right]A8[xy]=[864] has :AOption A.
