B is a 2x2 matrix with the property that there is an invertible 2x2 matrix R such that
R^-1BR = [(sqrt 3) 0 ] [ 1.2 -(sqrt 3)/2]
[ 0 (sqrt 3) ] [(sqrt 3)/2 1/2 ]
I know the first part is the scaling matrix and the second on in the rotation matrix.
I'm suppose to find B^6 which is equal to
B^6 = R^-1D^6R
But I dont know how I would find the matrix for R or D.
