6 : 2 ( 1 + 2)
= 6 : 2 x 3
= 3 x 3
= 9
\(6:2\left(1+2\right)\)
\(=6:2.3\)
\(=3.3\)
\(=9\)
_Chúc bạn học tốt_
6÷2(1+2)
=> 6÷6=1
k mk nha. Chúc bạn học giỏi

Vậy kết quả đúng ở bài này là bằng 9.
đâu phải câu này ai cũng ko làm được
90% sai u

<br class="Apple-interchange-newline"><div></div>6 : 2 (1 + 2)= 6 : 2 x (1 + 2)

= 9
\(6\) \(:\)\(2\)\(\left(1+2\right)\)
\(=\)\(6\) \(:\) \(2\)\(\left(1+2\right)\)
\(=\)\(6\) \(:\) \(2\)\(\times\)\(3\)
\(=\) \(3\) \(\times\) \(3\)
\(=\) \(9\)
Mk chắc chắn đúng luôn.
Giải thích nè:
-Theo quy luật thì ta ưu tiên ngoặc trước.
-Sau đó là làm từ trái sang phải.
-Cuối cùng là ra kết quả thôi.
\(6\div2\left(1+2\right)\)
\(=6\div2\times3\)
\(=3\times3\)
\(=9\)
Học tốt~
