Step 1
The given matrices are
A=[2i013i01+i80i10i1111]
and
D=[3000000000200001]
As order of both the matrices are same so multiplication is possible.
Step 2
AD=[2i013i01+i80i10i1111][3000000000200001]
AD=[6i023i001603i00i3021]
Now
DA=[3000000000200001][2i013i01+i80i10i1111]
DA=[6i039i00002i202i1111]
