Question

tim tat ca cac uoc cua 5,9,8,-13,1,-8 

Answer 1

\(Ư\left(5\right)=\left\{1;-1;5;-5\right\}\)

\(Ư\left(9\right)=\left\{1;-1;3;-3;9;-9\right\}\)

\(Ư\left(8\right)=\left\{1;-1;2;-2;4;-4;8;-8\right\}\)

\(Ư\left(-13\right)=\left\{1;-1;13;-13\right\}\)

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

\(Ư\left(-8\right)=\left\{1;-1;2;-2;4;-4;8;-8\right\}\)

Answer 2

5 = { 5 , -5 , 1 ,  -1}

9={9,-9 , 3 , -3 , 1 ,-1}

8 = {8 , -8 , 4 , -4 , 2 , -2 , 1 , -1 }

-13 = {13 , -13 , 1 , -1 }

1 ={1 , -1 }

-8 = { 8 , -8 , 4 , -4 , 2 , -2 , 1 , -1}

Answer 3

Ư(5) = {-5; -1; 1; 5}

Ư(9) = {-9; -3; -1; 1; 3; 9}

Ư(8) ={-8; -4; -2; -1; 1; 2; 4; 8}

Ư(-13) = {-13; -1; 1; 13}

Ư(1) = {-1; 1}

Ư(-8) = {-8; -4; -2; -1; 1; 2; 4; 8}
