cái bài này hình như là mình làm rồi

n+8 ⋮ n-2

⇒ (n-2)+10 ⋮ n-2

Vì (n-2) ⋮ (n-2)

⇒ 10⋮(n-2)

⇒(n-2)∈ Ư(10)

⇒(n-2)∈{-1,1,10,-10,2,-2,5,-5}

Lập bảng :

Vậy

n+8=n-2+10

n+8 chia hết cho n-2 => n-2+10 chia hết cho n-2

=>10 chia hết cho n-2

=> n-2 thuộc ước của 10 là các số {0;1;-1;2;-2;5;-5;10;-10}

n-2=0=>n=2

n-2=1=>n=3

n-2=-1=>n=1

n-2=2=>n=4

n-2=-2=>n=0

n-2=5=>n=7

n-2=-5=>n=-3

n-2=10=>n=12

n-2=-10=>n=-8

Vậy n={-8;-3;0;1;2;3;4;7;12} thì n+8 chia hết cho n-2

17 . 5 + 7 . 17 - 16 . 12

= 17 . ( 5 + 7 ) - 16 . 12

= 17 . 12 - 16 . 12

= 12 . ( 17 - 16 )

= 12 . 1

= 12

Mình đảm bảo 100% là đúng luôn

Mình từng làm những bài như này rồi

17.5+7.17-16.12

=17. ( 5 + 7 ) - 16 . 12

=17 . 12 - 16 . 12

=12 . ( 17 - 16 )

=12 . 1

=12
