x3+x3+xy+xy+xy

Answer 1

To find an expression equivalent to \( x^3(2 + y^5) \), we can use the distributive property (also known as the distributive law of multiplication over addition):

\[
x^3(2 + y^5) = x^3 \cdot 2 + x^3 \cdot y^5
\]

This simplifies to:

\[
2x^3 + x^3y^5
\]

Now, we can match this expression with the given responses:

1. **2x³ + y⁵**: This is not equivalent because it does not include the \( x^3 \) term multiplied by \( y^5 \).
2. **2x³ + x³y⁵**: This matches our derived expression.
3. **x³ + 2 + y⁵**: This is not equivalent because it suggests addition rather than multiplication and does not represent the original expression correctly.
4. **x³ + x³ + xy + xy + xy**: This simplifies to \( 2x^3 + 3xy \), which is also not equivalent to our expression.

Thus, the correct answer is:

**2x³ + x³y⁵**.
