123 x 30 + 123 x 70
= 123 x ( 30 + 70 )
= 123 x 100
= 12300
123 x 30 + 123 x 70
= 123 x ( 30 + 70 )
= 123 x 100
= 12300
123 x 30 + 123 x 70
= 123 x ( 30 + 70 )
= 123 x 100
= 12300
TK MK NHA CÁC BẠN MK ĐG BỊ ÂM ĐIỂM
123 x 30 + 123 x 70
= 123 x (70 + 30)
= 123 x 100
= 12300
123 x 30 + 123 x 70
= 123 x ( 30 + 70 )
= 123 x 100
= 12 300
123 x30 + 123 x 70
=123 x (30+70)
=123 x 100
=1230
123 x 30 + 123 x 70
= 123 x (70 + 30)
= 123 x 100
= 12300
Ủng hộ mk nha perfect shadow
123 x 30 + 123 x 70
= 123 x ( 30 + 70)
= 123 x 10
= 1230
123 x 30 + 123 x 70
= 123 x ( 30 + 70 )
= 123 x 100
= 12 300
123 x 30 + 123 x 70
= 123 x ( 30 + 70 )
= 123 x 100
= 12300
123 x 30 + 123 x 70
= 123 x ( 30 + 70 )
= 123 x 10= 12300
123x30+123x70
=123x(30+70)
=123x100
=12300
123 x 30 + 123 x 70
= 123 x ( 30 + 70 )
= 123 x 100
= 12300
123x30+123x70
=123x(30+70)
=123x100
=1230
Vậy 123x30+123x70=1230
\(123\times30+123\times70\)
\(=123\times\left(30+70\right)\)
123 x 30 + 123 x 70
= ( 30 + 70 ) x 123
= 100 x 123
= 12300 đó nha bn @perfect shadow
Tính nhanh
123 x 30 + 123 x 70 = 123 x ( 30 + 70 )
= 123 x 100
= 12300
Đây ko phải toán lớp 6 đâu nhá. Toán lớp 4 mới đúng
\(123\times30+123\times70.\)
\(=123\times\left(30+70\right)\)
\(=123\times100\)
\(=12300\)
\(123\times30+123\times70\)
\(=123\times\left(30+70\right)\)
\(=123\times100\)
\(=12300\)
