Answer 1

\(-17.\left(25-43\right)+25.\left(34+17\right)-19-193\)

\(=-17.\left(-18\right)+25.51-19-193\)

\(=306+1275-19-193\)

\(=1369\)

Answer 2

Cách 2 nhé:

\(-17.\left(25-43\right)+25\left(34+17\right)-19-193\)

\(=-17.25+17.43+25.34+25.17-19-193\)

\(=17.43+25.34-19-193\)

\(=731+850-19-193\)

\(=1369\)

Answer 3

−17. 25 − 43 + 25 34 + 17 − 19 − 193
= −17.25 + 17.43 + 25.34 + 25.17 − 19 − 193
= 17.43 + 25.34 − 19 − 193
= 731 + 850 − 19 − 193
= 1369

Answer 4

-17 . [ 25-43 ] + 25 . [ 34 +17 ] -19 -193

= -17 . [-18] + 25. 51-19 -193

= -17 . [-18] + 1275-19 -193

  = -17 . [-18] +1063

= 306+1063 = 1369
