I was just wondering if there is a way to show, using variables, this:(adsbygoogle = window.adsbygoogle || []).push({});

say:

[tex]A = \left(\begin{array}{cc}a&b \\ c&d \end{array}\right)[/tex]

[tex]A^n[/tex]

I was wondering if there is any way to show A^n as a formula of entries? just curious..

[tex]A^2[/tex]=[tex]A = \left(\begin{array}{cc}aa+cb&ab+bd \\ ca+cd&bc+dd \end{array}\right)[/tex]

the next entry for a is a^3+cab+bca+cdb which has nothing to do with the previous matrix... is there a theme to all this?
