[Đào Minh Hằng]

tìm 5 giá trị của x thỏa mãn 8<x<9

Answer 1

[Phùng Phạm Quỳnh Trang]

x=8,1;8,2;8,3;8,4;8,5

Answer 2

[Yen Nhi]

\(8=\dfrac{8}{1}=\dfrac{8\times6}{1\times6}=\dfrac{48}{6}\)

\(9=\dfrac{9}{1}=\dfrac{9\times6}{1\times6}=\dfrac{54}{6}\)

\(\Rightarrow\dfrac{48}{6}< x< \dfrac{54}{6}\)

\(\Rightarrow x\in\left\{\dfrac{49}{6};\dfrac{50}{6};\dfrac{51}{6};\dfrac{52}{6};\dfrac{53}{6}\right\}\)
