MathematicsHard244×since 2002Q4527Let A = \left( {\matrix{ 2 & { - 1} \cr 0 & 2 \cr } } \right). If B=I−5C1(adj A)+5C2(adj A)2− ..... −5C5(adj A)5B = I - {}^5{C_1}(adj\,A) + {}^5{C_2}{(adj\,A)^2} - \,\,.....\,\, - {}^5{C_5}{(adj\,A)^5}B=I−5C1(adjA)+5C2(adjA)2−.....−5C5(adjA)5, then the sum of all elements of the matrix B isA−-−5B−-−6C−-−7D−-−8Check answerSkip
