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]
