where you are givenAandCand are told to figure outX, you would like to "divide off" the matrixA. But you can't do division with matrices. On the other hand, what if you could find the inverse ofA, something similar to finding the reciprocal fraction above?

After finding the diagonal, the P matrix, and the inverse of P, I'm setting them equal to An (with the numeric digits in the diagonal also set to the nth power). The cross produce of these three matrices supposedly give me the power formula of the base matrix A. Example: A 3x3 ...
