I will be apperciate that some one could help me?
thanks.

clc
syms x
M=[x 2*x 3*x; 4*x 5*x 6*x; 7*x 8*x 9*x];

You can access them by indexing:
syms x
M=[x 2*x 3*x; 4*x 5*x 6*x; 7*x 8*x 9*x];
M(2,3)
ans = 
However, you should be mindful that you can also integrate as a matrix, without extracting one element at a time:
int(M,0,1)
ans =
