To rewrite the expression \( x^{10} \cdot y^{20} \) using the Commutative Property of Multiplication, you can simply change the order of the factors. The Commutative Property states that changing the order of multiplication does not change the product.
Therefore, you can rewrite the expression as:
\[ y^{20} \cdot x^{10} \]
Both \( x^{10} \cdot y^{20} \) and \( y^{20} \cdot x^{10} \) are equivalent.
