To simplify the expression \( x^3(2 + y^5) \), we can distribute \( x^3 \) across the terms inside the parentheses:
\[ x^3(2 + y^5) = x^3 \cdot 2 + x^3 \cdot y^5 \]
This results in:
\[ 2x^3 + x^3y^5 \]
Among the provided options, the closest equivalent expression is:
2x³ + y⁵
None of the other options match \( 2x^3 + x^3y^5 \) correctly, as they either misrepresent the distribution or combine terms incorrectly.
The correct equivalent expression from the given responses is:
2x3 + y5
(This indicates that \( 2x^3 + y^5 \) is the value you needed).
