1.Let A=(a12101210)A = \begin{pmatrix} a & 1 & 2 \\ 1 & 0 & 1 \\ 2 & 1 & 0 \end{pmatrix}A=a12101210 andB=I+adj(A)+(adj A)2+⋯+(adj A)10.B = I + \text{adj}(A) + (\text{adj}\,A)^{2} + \cdots + (\text{adj}\,A)^{10}.B=I+adj(A)+(adjA)2+⋯+(adjA)10.Then, the sum of all the elements of the matrix BBB is:a.−124-124−124b.222222c.−88-88−88d.−110-110−110Login to continueOnly logged in users canattempt or see the solution.
