Question

Bội và ước của một số nguyên

B₍₃₎ = .......

B_(-3) = ......

Ư_(-3) = ......

Ư₍₆₎ = .......

Ư₍₁₁₎ = ........

Ư_(-1) = .........

Answer 1

B (3) = {...;-12; -9; -6; -3; 0; 3; 6; 9; 12;...}

B (-3) = {...;-12; -9; -6; -3; 0; 3; 6; 9; 12;...}

Ư (-3) = {-3; -1; 1; 3}

Ư (6) = {-6; -3; -2; -1; 1; 2; 3; 6}

Ư (11) = {-11; -1; 1; 11}

Ư (-1) = {-1; 1}.

Answer 2

B(3)={0;3;6;9;...}

B(-3)= {0;-3;3;6;9;...}

Ư(-3)={-3;-1;1;3}

Ư(6)={-6;-3;-2;-1;1;2;3;6}

Ư(11)={-11;-1;1;11}

Ư(-1)={-1;1}

Answer 3

\(B\left(3\right)=\left\{...;-9;-6;-3;0;3;6;9;...\right\}\)

\(B\left(-3\right)=\left\{...;-9;-6;-3;0;3;6;9;...\right\}\)

\(Ư\left(-3\right)=\left\{-3;-1;1;3\right\}\)

\(Ư\left(6\right)=\left\{-6;-3;-2;-1;1;2;3;6\right\}\)

\(Ư\left(11\right)=\left\{-11;-1;1;11\right\}\)

 

\(Ư\left(-1\right)=\left\{-1;1\right\}\)
