If M and N are two matrices given by M=∑k=110A2kM = \sum\limits_{k = 1}^{10} {{A^{2k}}}M=k=1∑10A2k and N=∑k=110A2k−1N = \sum\limits_{k = 1}^{10} {{A^{2k - 1}}}N=k=1∑10A2k−1 then MN² is :Aa non-identity symmetric matrixBa skew-symmetric matrixCneither symmetric nor skew-symmetric matrixDan identity matrixCheck answerSkip
