Xin mọi người đừng k sai mình nhé !

= 35 .( 34 + 1 ) + 38 + 65 ( 75 + 45 )

Chúc bạn học tốt 

 35 × 34 + 34 × 38 + 65 × 75 + 65 × 45

= 34 × (35 + 38) + 65 × (75 + 45)

= 34 × 73 + 65 × 120

= 2482 + 7800

= 10282

\(35\cdot34+70\cdot38+65\cdot75+65\cdot35\)

\(=35\cdot34+35\cdot76+65\cdot\left(75+35\right)\)
