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?

Yes, Peter simplified his work completely. The expression x3 • x3 • x3 • x3 is equal to x3+ 3 + 3 +3. It would not be the same as x3 + x3 + x3 + x3. This is in accordance with rules for exponents which is ( x^m ) ( x^n ) = x^( m + n ). Hope this answers the question.
