If A=(1002)A = \begin{pmatrix} 1 & 0 \\ 0 & 2 \end{pmatrix}A=(1002), what is A3A^3A3?
(1008)\begin{pmatrix} 1 & 0 \\ 0 & 8 \end{pmatrix}(1008)
(1006)\begin{pmatrix} 1 & 0 \\ 0 & 6 \end{pmatrix}(1006)
(3006)\begin{pmatrix} 3 & 0 \\ 0 & 6 \end{pmatrix}(3006)
(1002)\begin{pmatrix} 1 & 0 \\ 0 & 2 \end{pmatrix}(1002)
