#)Giải :
\(\left(-167\right).\left(67-34\right)-67.\left(34-167\right)\)
\(=167.67+167.34-67.34+67.167\)
\(=167.36-67.34\)
\(=34\left(167-67\right)\)
\(=34.100\)
\(=3400\)
(-167) . ( 67 - 34 ) - 67 . ( 34 - 167 )
= (-167) . 67 + 167 . 34 - 67. 34 + 67 . 167
= ( -167 . 67 + 67 . 167 ) + 34 . ( 167 - 67 )
= 0 + 34 . 100
= 3 400

Trả lời bài sau :
(- 167 ) . ( 67 - 34 ) - 67. (34 - 167 )
=167.67 + 167.34 - 67.34 + 67.167
=167.36 - 67.34
=34(167 - 67 )
=34.100

k mik nhé
(-167) . (67-34) - 67 . (34-167)
=(-167).67+167.34-67.34+167.67
=(-167.34+167.34)+167.34-67.34
=0+34(167-67)
= 34.100
=3400
\(\left(-167\right).\left(67-34\right)-67.\left(34-167\right)\)
\(=\left(-167\right).67-\left(-167\right).34-67.34+67.167\)
\(=67.\left[\left(-167\right)+167\right]-34.\left[\left(-167\right)+67\right]\)
\(=67.0-34.\left(-100\right)\)
\(=0-\left(-3400\right)=3400\)
