Theoretical diagonalazation question

  1. Mar 2, 2009 #1
    there is
    A\epsilon M_{2x2}(Q)
    I am given that A is diagonazable
    prove that
    is diagonizable too

    B)give an example for a matrix B\epsilon M_{2x2}(Q)
    that is not diagonizable,but b^2 is diagonisable

    i know that the eigenvalues of a matrix are the same as for every matrix
    like A^10 or A^3+2A+3I etc..

    but i dont now how to show what they ask
