4.1100 1000 0001 0001 1001 0000 0000 1000

Answer 1

refer to your instruction set architecture (ISA) (some reference sheet that breaks down all the instructions and what they do, and what fields are at what bits of the instruction). an example ISA you can google is the "mips green sheet"

once you find how your instruction is broken down by the fields, first determine the opcode, then determine each field of your instruction and go from there.
