Lec - 05 Beauty of Matrices | Sum of Each Row is 1 | IIT JAM | CSIR UGC NET | GATE MA | B Sc Maths

[sanjughosh]

Here in this video the answer of last question is wrong according the corresponding theory.because in that 3×3 matrix A sum of each column of that matrix is 3.so sum of each column of A^3 is 3^3=27 and sum of all elements in A^3 is =3×27=81
