Final answer:
To simplify the expression x(x^5 + 7), distribute x to each term inside the parentheses and combine like terms.
Step-by-step explanation:
To simplify the expression x(x^5 + 7), we need to distribute the x to each term inside the parentheses using the distributive property. This gives us x^6 + 7x, since x^1 * x^5 = x^6. Therefore, the simplified expression is x^6 + 7x.
