Che cos'è un monomio?

Type response here

Multiple Select

Segna i monomi tra le seguenti espressioni algebriche:

$2aba^3$

$2\left(a+b\right)$

$4a^3-b^2$

$\frac{1}{2}a^6$

Multiple Select

Se riduco in forma normale il monomio

ottengo

$18ab$

$18a^2b$

$18ba^2$

$9a^2b$

Multiple Choice

Se riduco in forma normale il monomio

12a^2b^3\left(-2\right)a^3

ottengo

$24a^5b^4$

$-24a^5b^3$

$-16b^3a^5$

$-10a^5b^3$

Multiple Select

Segna le affermazioni vere relative al monomio

x^2yz^3

il coefficiente è 1

la parte letterale è $xyz$

le variabili sono x, y, z

la parte letterale è $x^2yz^3$

non ha coefficiente

Esercizi
