Step 1
Multiply the first set of matrices as,
=[2310]×[4121]
=[2310]×[4121]
=[2(4)+3(2)2(1)+3(1)1(4)+0(2)1(1)+0(1)]
=[8+62+34+01+0]
=[14541]
Thus, the multiplication gives [2310]×[4121]=[14541]
Step 2
Multiply the second set of matrices as,
[134512]×[214310]
[134512]×[214310]
=[1(2)+3(3)1(1)+3(1)1(4)+3(0)4(2)+5(3)4(1)+5(1)4(4)+5(0)1(2)+2(3)1(1)+2(1)1(4)+2(0)]
=[2+91+34+08+154+516+02+61+24+0]
=[112423116814]
Thus, the multiplication gives [134512]×[214310]=[112423116814]
