How to find Cube of a matrix?

Answers

Answered by Tia1520

first multiple it with itself once..
then multiply that result with the original matrix again..
see cube means any number multiplied three times by itself.
as in a*a*a will give you "a" cube ..
thus apply the same concept and get the results
I hope u are answered.

sankalp07: but during multiplication of matrix the order of multiplication matters. a×a gives me a new matrix say b. so how do i know that to get a×a×a i should multiply b×a or a×b

sankalp07: b×a and a×b will give different answers. so what should i do?

Tia1520: but you are multiplying the same matrix so how will you get different answers and also the order remains same

Tia1520: because the matrix never changes so whatever be the order of the matrix you will your final answer that same way

sankalp07: ok thank u very much
