The Commutative Property of Addition states that changing the order of the addends does not change the sum. Therefore, we can rewrite the expression \( j^3 + h^4 \) by switching the order of the terms:
\[ h^4 + j^3 \]
So, the expression \( j^3 + h^4 \) can be rewritten as \( h^4 + j^3 \) using the Commutative Property of Addition.
