Najpierw uporządkujemy jednomiany:

---

I.

$\underline{2}\underline{\underline{x}}\cdot \underline{3}\underline{\underline{x^2}}\cdot \underline{\left(-3\right)}\cdot y\cdot \left(\underline{-2}{y}^3\right)=36x^3{y}^4$

---

II.

$\underline{2}\underline{\underline{x^2}}\cdot \underline{3}\underline{\underline{x^2}}\cdot \underline{\left(-3\right)}\cdot y\cdot \underline{2}{y}^3=-36x^4{y}^4$  

---

III.

$\underline{2}\underline{\underline{x^2}}\cdot \underline{3}\underline{\underline{x^2}}\cdot \underline{\left(-3\right)}\cdot y\cdot \underline{\left(-2\right)}\cdot y^3=36x^4{y}^4$ 

---

IV.

$\underline{2}\underline{\underline{x}}\cdot \underline{3}\underline{\underline{x^2}}\cdot \underline{\left(-3\right)}\cdot y\cdot \underline{2}{y}^4=-36x^3{y}^4$

Wpisujemy:

I - D

II - B

III - A

IV - C
