20,22 x 109 - 20,22 : 0,1 + 20,22
= 20,22 x 109 - 20,22 x 10 + 20,22 x 1
= 20,22 x (109 - 10 + 1)
= 20,22 x 100
= 2022
20,22x109-20,22:0,1+20,22
=20,22 x 109 - 20,22x10 + 20,22x1
=20,22x(109-10+1)
=20,22x100
\(\Rightarrow\)2022
20,22 x 109 - 20,22 : 0,1 + 20,22
= 20,22 x 109 - 20,22 x 10 + 20,22 x 1
= 20,22 x (109 - 10 + 1)
= 20,22 x 100
= 2022
Chúc bạn học tốt ^^
