假设$C=AB$, 那么答案就为
$egin{align} otag ans & =sumlimits_{i=0}^{n-1}sumlimits_{j=0}^{n-1}C[i][j]p^{(n-i)n-1-j} \ otag & = sumlimits_{i=0}^{n-1}sumlimits_{j=0}^{n-1}sumlimits_{k=0}^{n-1}A[i][k]B[k][j]p^{(n-i)n-1-j} \ & = sumlimits_{k=0}^{n-1}Big(sumlimits_{i=0}^{n-1}A[i][k]p^{(n-i)n-1}Big)Big(sumlimits_{j=0}^{n-1}B[k][j]p^{-j}Big) otag end{align}$
