Ta có : \(69\cdot\left(-32\right)-32\cdot\left(-49\right)\)
\(=69\cdot\left(-32\right)+\left(-32\right)\cdot\left(-49\right)\)
\(=\left(-32\right).\left(69-49\right)\)
\(=\left(-32\right).20=-640\)
69.(-32) - 32.(-49)
= - 32 . ( 69 - 49 )
= - 32 . 20
= - 640

\(69\left(-32\right)-32\left(-49\right)\)
\(=-2208-15568=-640\)
Trl:
69.(-32) - 32.(-49)
= -32 . ( 69 - 49 )
= -32 . 20
= -640
Hc tốt
Trả lời :
69 . ( - 32 ) - 32 . ( - 49 )
= - 32 . ( 69 - 49 )
= - 32 . 20
= - 640
