Answer:

4[tex]m^{2}[/tex][tex]k^{2}[/tex]  ;28[tex]k^{2}[/tex]  ;8 km

9m[tex]m^{2}[/tex]k;63mk;  18[tex]m^{2}[/tex]

Step-by-step explanation:

4k·[tex]m^{2}[/tex]k=4[tex]m^{2}[/tex][tex]k^{2}[/tex]

4k·7k=28[tex]k^{2}[/tex]

4k·2m=8km

9m·[tex]m^{2}[/tex]k=9m[tex]m^{2}[/tex]k

9m·7k=63mk

9m·2m=18[tex]m^{2}[/tex]

Se multiplican los números y luego las letras

Si se multiplican dos letras iguales lo elevamos al cuadrado

EJEMPLO:m· m=[tex]m^{2}[/tex]
