Hello everyone, I am kind of new in the whole linear algebra subject. My teacher gave me a question that I struggled with. I was requested to find x from a given equation: ABC^tx^1BA^tC=AB^t Basically, he manipulated the equation in A^tB^1A^1 and I didn't understand the whole idea inside the solution, so I will be really glad if someone can help me with the confusion.

Well, IF that is your equation, then: x = [A^t * C^(t+1)] / [B^(t2)] Can be "shown" this way: x = A^t * C^(t+1) * B^(2t) Remember that x^(1) = 1/x Last edited by Denis; March 21st, 2018 at 10:03 AM.
