To determine which expression is equivalent to \( x^3(2 + y^5) \), we can distribute \( x^3 \) into the parentheses:
\[ x^3(2 + y^5) = x^3 \cdot 2 + x^3 \cdot y^5 = 2x^3 + x^3y^5. \]
Now, let's review the provided responses:
- \( 2x^3 + y^5 \)
- \( x^3 + x^3 + xy + xy + xy \)
- \( 2x^3 + x^3y^5 \)
- \( x^3 + 2 + y^5 \)
The correct expression that matches our simplified result \( 2x^3 + x^3y^5 \) is option 3:
3) \( 2x^3 + x^3y^5 \).
This is the equivalent expression.
