Description: For a 3*3 matrix M, let \operatornametrace(M) denote the sum of all the diagonal elements of M. Let A be a 3*3 matrix such that |A|=\dfrac12 and \operatornametrace(A)=3. If B=\operatornameadj(\operatornameadj(2A)), then the value of |B|+\operatornametrace(B) equals: | Watch the step-by-step video solution for this NIMCET PYQ.
