\(3+3.4+3.2\)
\(=3.\left(1+4+2\right)\)
\(=3.7\)
\(=21\)
3 + 3 x 4 + 3 x 2
= 3 x ( 1 + 4 + 2 )
= 3 x 9
= 27
Chúc bạn học giỏi !!!!
3 + 3 x 4 + 3 x 2
=3 x ( 1 + 4 + 2 )
= 3 x 7
=21
3 + 3 x 4 + 3 x 2
= 3 x ( 1 + 4 + 2 )
= 3 x 7
= 21
\(3+3.4+3.2=\)\(3+12+6\)=\(15+6=21\)
3 + 3 x 4 + 3 x 2 = 3 x 2 x 4 + 3 x 2
= 3 x 6 + 3 x 2
= 3 x ( 6 + 2 )
= 3 x 8
= 24
3 + 3 x 4 + 3 x 2
= 3 ( 1 + 4 + 2 )
= 3 x 7
= 21
3 + 3 × 4 + 3 × 2
= 3 × ( 1 + 4 + 2 )
= 3 × 7
= 21
