\(1994x867+1995x133\)
\(=1994x867+\left(1994+1\right)x133\)
\(=1994x867+1994x133+133\)
\(=1994x\left(867+133\right)+133\)
\(=1994x1000+133\)
\(=1994000+133\)
\(=1994333\)
Chúc bạn học tốt !!!!
1994 nhân 867+1995*133=1994*867+1994*133+133=1994*1000+133=1994133
1994 x 867 + 1995 x 133 = 1994 x 867 + ( 1995 - 1 ) x 133 +133
=1994 x ( 867 + 133 ) +133
= 1994 x 1000 +133
= 1994000+133
1994133
