1234*89+1234+1234*10
=1234*(98+1+10)
=1234*100
=123400
1234 x 89 + 1234 x 1 + 1234 x 10
= 1234 x ( 89 + 1 + 10 )
= 1234 x 100
= 123400
1234x89+1234+1234x10
=1234x(89+10)+1234
=1234x(99+1)
=1234x100
=123400
\(1234\left(89+1+10\right)=1234.100=123400\)
1234 x 89 + 1234 + 1234 x 10
= 1234 x ( 89 + 10+ 1 )
= 1234 x 100
= 123400
1234 x 89 + 1234 + 1234 x 10
=1234 x 89 + 1234 x 1 + 1234 x 10
= 1234 x ( 89 + 10 + 1 )
= 1234 x 100
= 123400
là 123400 nha nue dung ket bạn voi minh nha
