If X =
I did this
I used the law of indices, is it right to apply this for matrices?
Please help me, I am not sure if I did it right here!
I thought I could not change the order within the multiplication, but so is it that I can do it in thie case? Why?
X^3 = (P^(-1)PA)(P^(-1)PA)(P^(-1)PA)
= P^(-3) (PA)^3
Wait, I did this using laws of indices again, can you please explain how to do it, I'm afraid I do not understand..
Thank you ever so much!
