Secret messages can be encoded by using a code and an encoding matrix. If we have the code: 
and an encoding matrix: E = 
, we can encode a message by taking every two letters of the message, converting them to their corresponding numbers, creating a 
/> matrix, and then multiplying each two numbers by E. Use the code and encoding scheme above and an additional encoding matrix, F = 
, to answer the question.If the letters to be encoded are L = 
, show that (E + F)L = EL + FL.
