4,25 x 57,43 - 325 + 42,57 x 4,25
= (4,25 x 57,43 + 42,57 x 4,25) - 325
= 4,25 x (57,43 + 42,57) - 325
= 4,25 x 100 - 325
= 425 - 325
= 100
4,25 x 57,43 - 325 + 42,57 x 4,25
= (4,25 x 57,43 + 42,57 x 4,25) - 325
= 4,25 x (57,43 + 42,57) - 325
= 4,25 x 100 - 325
= 425 - 325
= 100
---------------------------------------------------
= ( 4,25 x 57,43 + 42,57 x 4,25 ) - 325
= 4,25 x ( 57,43 + 42,57 ) - 325
= 4,25 x 100 - 325
= 425 - 325 = 100
Ta có
4,25 x 57,43 - 325 + 42,57 x 4,25
= (4,25 x 57,43 + 42,57 x 4,25) - 325
= 4,25 x (57,43 + 42,57) - 325
= 4,25 x 100 - 325
= 425 - 325
= 100
