Final answer:
To simplify the expression x⁸ + x⁴ + 1, there are no like terms to combine, so we can't simplify it further. Similarly, for the expression m⁷ + m³ + m², there are no like terms to combine, so the expression can't be simplified any further.
Step-by-step explanation:
To simplify the expression x⁸ + x⁴ + 1, there are no like terms to combine, so we can't simplify it further. Therefore, the simplified expression is x⁸ + x⁴ + 1.
Similarly, to simplify the expression m⁷ + m³ + m², there are no like terms to combine, so the expression can't be simplified any further. The simplified expression is m⁷ + m³ + m².
