The expression you provided is \( x^3 (2 + y^5) \). This expression is already in its simplest form.
However, if you're looking to distribute \( x^3 \) through the terms inside the parentheses, you would get:
\[ x^3 \cdot 2 + x^3 \cdot y^5 = 2x^3 + x^3y^5 \]
So, both \( x^3 (2 + y^5) \) and \( 2x^3 + x^3y^5 \) are equivalent expressions.
