325 × 1574 - 325 × 325 - 325 × 249

= 325 × (1574 - 325 - 249)

= 325 × 1000

= 325000.

Ai k mình mình k lại.

325 x 1574 - 325 x 325 - 324 x 249

1074 nha bn

325 x 1574 -325 x 325 - 325 x 249= 325 x ( 1574-325-249)=325 x 1000= 325000

2 x 8 x 50 x 25 x 125 = ( 2 x 50) x ( 8 x 125) x 25 = 100 x 1000 x 25=2500000

k cho mình nha!!!

325-25.x=325-25

325-25.x=300

25.x=325-300
