Let A be a 3 * 3 matrix such that |\operatornameadj(\operatornameadj(\operatornameadj \mathrmA))|=81. If S=\left\n \in \mathbbZ:(|\operatornameadj(\operatornameadj A)|)^(n-1)^2/2=|A|^\left(3 n^2-5 n-4\right)\right\, then ∑_\limitsn \in S\left|A^\left(n^2+n\right)\right| is equal to : | Watch the step-by-step video solution for this NIMCET PYQ.
