57 x 12 + 57 x 13 + 57 x 16
= 57 x (12 + 13 + 16)
= 57 x 41
= 2337
57 x 12 + 57 x 13 + 57 x 16
= 57 x (12 + 13 + 16)
= 57 x 31
= 1767
57 x 12 + 57 x 13 + 57 x 16
= 57 x ( 12 + 13 + 16 )
= 57 x 41
= 2337
57 x 12 + 57 x 13 + 57 x 16
57 x 12 + 57 x 13 + 57 x 16
= 57 x ( 12 + 13 + 16 )
= 57 x 41
= 2 337.
=57.(12+13+16)
=57.41
=2337
đề tự ghi nha
k mik nhé
\(57.12+57.13+57.16\)
\(=57\left(12+13+16\right)\)
\(=57.41\)
\(=2337\)
57 x 12 + 57 x 13 + 57 x 16
= 57 x ( 12 + 13 + 16)
= 57 x 41
= 2337
5 7.12 + 57.13 + 57.16=57. (12 + 13 + 16)
=57.41
=2337.
Chúc học tốt !!!!
