Hi...I'm trying to figure out this homework question, and it's the only question I've been truly stuck on.

Write the assembly language instructions to put the largest unsigned contents of memory locations $3000 and $3001 into memory location $4000

I don't even know where to start, I would imagine I have to use compare instructions, but I can't figure out how to use them. Any help would be appreciated. The answer with an explanation I can follow would be best. I know we don't like to just give answers out on here, but I think having the answer will be the only way I can learn how to do this sort of thing. Thanks!!!
