\(B1:\)-Ta xát tổng của M

48  chia hết cho 4

20 chia hết cho 4 

Ta áp dụng công thức a chia hết cho d;b chia hết cho d;c chia hết cho d

=>a+b+c chia hết cho d

=>Để m chia hết cho 4 thì a cũng phải chia hết cho 4

Để M không chia hết cho 4 thì a phải không chia hết cho 4

\(B2:\)1x2x3x4x5x...x20

=(5x20x4)x1x2x3x...

=400x1x2x3x...

Ta có 400 chia hết cho 400

Ta áp dụng công thức

a chia hết cho b thì a nhân với bất kì số nào cũng chia hết cho b

=>A chia hết cho 400

\(B3:\)Ta có n+10 chia hết cho n+1;n+1 chia hết cho n+1

=>(n+10)-(n+1) chia hết cho n+1

a,(n+10)-(n+1)=9

=>9 là bội của n+1

Ư(9)=(1;-1;3;-3;9;-9)

=.n=(0;-2;-4;2;8;-10
