To find an equation that is equal to \( x^3(2+y^5) \), we can expand it. The expression can be rewritten as follows:
\[ x^3(2+y^5) = x^3 \cdot 2 + x^3 \cdot y^5 = 2x^3 + x^3y^5 \]
So, an equivalent equation would be:
\[ 2x^3 + x^3y^5 \]
You can use this form or the original factored form, depending on your preference or the context in which you're working. If you need a specific type of equation or want to manipulate this further, please provide more details!
