To match each starred cards (⭐) with diamond cards (💎), we need to look for equivalent algebraic expressions based on exponents of \( x \) and \( y \).
Here’s how we can match them:
1. **\( \frac{1}{x} \) (⭐)** can be matched with **\( x^{-1} \) (💎)** because \( \frac{1}{x} = x^{-1} \).
2. **\( \frac{3}{x^4} \) (⭐)** can be matched with **\( 3x^{-4} \) (💎)** for the same reason: \( \frac{3}{x^4} = 3x^{-4} \).
3. **\( y^3x^2 \) (⭐)** can be matched with **\( x^2y^3 \) (💎)** because these two expressions are equivalent regardless of the order (commutative property of multiplication).
4. **\( x^{-2}y^3 \) (⭐)** can be matched with **\( x^{-2}y^3 \) (💎)** as they are the same expression.
5. **\( \frac{1}{x^3} \) (⭐)** can be matched with **\( x^{-3} \) (💎)** since \( \frac{1}{x^3} = x^{-3} \).
6. **\( 1 \) (⭐)** remains unmatched as there is no specific partner among diamonds that is equivalent.
7. **\( 3x^2 \) (⭐)** can also remain unmatched as there is no specific partner among diamonds that is equivalent.
Therefore, the matches are:
1. \( 1/x \) ⭐ matches (x^{-1}) 💎
2. \( 3/x^4 \) ⭐ matches (3x^{-4}) 💎
3. \( y^3*x^2 \) ⭐ matches (x^2*y^3) 💎
4. \( x^{-2}y^3 \) ⭐ matches (x^{-2}y^3) 💎
5. \( 1/x^3 \) ⭐ matches (x^{-3}) 💎
Remaining unmatched cards are:
- \( 1 \) ⭐
- \( 3x^2 \) ⭐
You can now proceed with these matches as per the directions provided on the screen for the drag and drop action.
