Respuesta :

Answer:

[tex]\left\begin{array}{ccccc}&6&7&5&0\\-&3&8&9&4\\--&--&--&--&--\\=&2&8&5&6\end{array}\right[/tex]

Step-by-step explanation:

[tex]\left\begin{array}{ccccc}&6&*&5&*\\-&*&8&*&4\\--&--&--&--&--\\=&2&8&5&6\end{array}\right[/tex]

  • 10-4=6

Therefore the last digit of 6*5* is 0.

  • [(5-1)+10]-5=9
  • 8+8+1=17
  • 6-(1+2)=3

Therefore:

[tex]\left\begin{array}{ccccc}&6&7&5&0\\-&3&8&9&4\\--&--&--&--&--\\=&2&8&5&6\end{array}\right[/tex]
