The expression \( x^3(2+y^5) \) can be distributed as follows:
\[ x^3(2+y^5) = x^3 \cdot 2 + x^3 \cdot y^5 = 2x^3 + x^3y^5 \]
However, since none of the responses provided correctly match the distribution, we should examine the closest option.
The response "2x3 + x3y5" would be equivalent to the expression, taking into account \( x^3(2 + y^5) \), since \( 2x^3 + x^3y^5 \) is the expanded version of the original expression.
Thus, the most accurate response from the list is:
2x3 + x3y5
