Considere as matrizes !$ R = { \begin{bmatrix} 4\,\,\,(16)^y\,\,\,-1\\9^\times\,\,\,\,\,\,\,\,a\,\,\,\,\,\,\,\,0 \end{bmatrix}} !$; !$ S = { \begin{bmatrix} 1\,\,\,\,(4)^{(2y -1)}\,\,\,\,2^{-1}\\3^\times\,\,\,\,\,\,\,\,b\,\,\,\,\,\,\,\,1 \end{bmatrix}} !$e !$ T = { \begin{bmatrix} b\,\,\,\,\,(2)^{( 2y -1)}-10\,\,\,\,\,c\\27\,\,\,\,\,\,\,\,\,\,13\,\,\,\,\,\,\,\,-6 \end{bmatrix}} !$ . A soma dos quadrados das constantes reais x,y,a,b,c que satisfazem à equação matricial !$ R - 6S = T !$ é
