ma puteti ajuta va rog frumos ? fie matricea A (1 1 ) ( 0 1 ) sa se calculeze A la a 2 +A + I la a 2

Răspuns :

[tex]A^2+A+I_{2}=\left[\begin{array}{ccc}1&2\\0&1\\\end{array}\right]+\left[\begin{array}{ccc}1&1\\0&1\\\end{array}\right] + \left[\begin{array}{ccc}1&0\\0&1\\\end{array}\right]= \left[\begin{array}{ccc}3&3\\0&3\\\end{array}\right][/tex]
