While simplifying some math work, Peter wrote on his paper that x3 • x3 • x3 • x3 equaled x3+3+3+3. Did Peter simplify his work correctly and completely to a final answer? Would Peter’s work be the same if he were to simplify x3 + x3 + x3 + x3?

I understand what the question is saying, but I don't know what property I would use to support the fact whether it is right or wrong. I looked through my lesson and notes a billion times. Can someone help me through it and not just tell me the answer?
